Are PlusNet speeds in meltdown?


[link to this post]
 
So a peek at a massive thread elsewhere and a few people seeing single thread issues and signs on congestion on even multi-thread.

Is this widespread and thus ISP meltdown, or just the face of contention appearing on a few nodes for a few weeks on what is a consumer priced service?

Mine's been very slow for the last few days with constant website not responding messages particularly in the evenings which for me suggests congestion somewhere. After 10pm last night, it was unusable as my quality monitor shows:

Hi WelshWarrior,

For completeness I should have included my ping test.. I'm only 30 miles south of London so that's going make some difference.

It looks as if we swapped gateway sometime this morning... might reboot the router and see if we can get onto a better gateway.

download speed is ok, depending on how good your speedtest is, the 45 burst isa bit iffy I think considering I am only up to 38, so even the 40 is a bit iffy.

Upload is naff.

The issues reported have been about Peak time mainly So anytime from 7pm through to 11.30 or midnight , (8pm-10pm) being the time slot when it has been at it's worst
In the past there have been severe increases in latency visiable on the ping monitor as well as low throughput, i hopped onto one gateway and the endpoint must have been 99% saturated latency of over 100ms and throughput both up and downstream sub 10mbps , and thats on a 80/20 FTTC product syncing at the full rates on fast path

I'm inclined to go with it being congestion on the backhaul (whether it's PlusNet's of BTw's issue I don't know), that's now becoming more apparent as more people move over to fibre based services, and thus higher broadband speeds.

The thing with PlusNet (and this is a good thing in my opinion) is that they're more open about this than most providers, and customers are maybe a little more willing to discuss it and try to get to the bottom of the problem.

It's always seemed to me that if we all switch from watching tv on the tv to watching tv and everything else (Netflix, catch up, i-player) via our phone line then the infrastructure, sooner or later, ain't going to cope

I read threads on here every day about fibre customers finding that when next door gets fibre installed the speed goes down with a bump. I've stayed with ADSL exactly for that reason and, dare I say it, my speed has marginally improved as others in the road have gone from ADSL to fibre

But if we all try to use the "phone line" to watch video (and HD and 4k video + games as well) something has to give whichever ISP we use

No issues seen by me.

Speedtests are as expected for a 40 meg capped service.

http://www.thinkbroadband.com/speedtest/results.html...

However, I do not expect perfection every second of every day that some customers appear to expect in the thread on the PN forums.

The odd blip is to be expected.

One customer appeared to be complaining about a 1% speed loss at peak times.

God, they still haven't fixed this yet?

The problem is definitely Plusnet-specific.

Last I heard Plusnet were still in denial about this, and still hiding their network latency graphs which they used to boast of once upon a time.

Occasionally feels like contention, but generally downloads and streaming are fine, so I assume the traffic management is working. Some more esoteric websites / protocols are at peak hours sometimes feel a bit off using the application.

However latency seems okay from my BQM graph, despite the peaks from my netflix usage wink

I noticed an extremely small spike in average latency (<2ms) during Christmas/New Year but it has been fine since, this has to be a regional issue. I've had absolutely no issues since the start of January here in central Scotland.

This was done yesterday afternoon: TBB Speedtest

Hasn't changed much: Quality Monitor

Never encountered any packet loss either, even during Christmas and New Year.

I am seeing congestion issues today on speed test, however not really noticing anything on just browsing (it's allow slow at 1m). The connection has only been up since midday (possibly BT working on telephone lines getting ready for FTTC)

I would run with something in between - there's contention somewhere on the consumer priced service and it seems fairly widespread though the cause is clear.

For me it hasn't been especially service affecting as I've been able to do everything I've wanted to. There has been some impact but as you rightly mentioned it is a pile high, sell cheap service.

Latency is higher at peak, speeds are slower, it's not been a killer.

For reference here's the current latency to the Beeb - it's excellent.

rtt min/avg/max/mdev = 12.420/12.475/12.689/0.102 ms

I'll post later once the congestion monster starts to do his thing.

Slow PC, proxy or av software issue I'd suggest, hence the horrid latency.

Clue is the long gap with no speed at the start.

I'm getting occasional awful VoIP quality where what I'm hearing is significantly slowed for a few seconds, then there's a click and it catches up again. It's only happening in the evenings.

I've been using VoIP for a considerable time and it's only started happening recently.

No, but it is just pot luck if you happen to be on a endpoint that isn't as saturated as some of them clearly are, Try dropping PPPOE session a few times in particular in between 9:30 -10pm and check that again,
Although apart from a terrible Sunday night peak time, things according to the ping monitors haven't been as bad as they where last week, but we are only on Tuesday and tonight isn't over yet

Recent Sunday nights have shown a spike in traffic around the time TopGear used to be on from a couple of peering charts - so that combined with the big boost in traffic from tablets, chromecasts, phones since Christmas are another factor.

Not really noticed anything then again I've been playing about with my routing over the last couple of days because I decided to get the VM line I was originally using as a backup bumped to 152M.

Also my PlusNet is on a Business tariff so not sure if that makes a difference, most traffic types are weighted the same by their QOS but a couple of things are slightly higher priority than residential.

That site doesn't respond to pings. Many use firewalls to block ping. (ICMP ECHO).

You're describing congestion in some transit links and no others. That would show up in pings and in traceroutes and other diagnostics.

I'm wondering if there is some BTwholesale core network congestion. We can't see this as all our traffic is in a PPPoE tunnel across the BTwholesale network.

Yep but also could be compounded by routing (not saying it is) because congestion itself can show the same symptoms.

For it to be a issue with BTW then it would also be affecting customers with every isp that uses BT WBMC shared for Backhaul . and there has been a distinct lack of such reports , The core network from what i have read would be the least unlikely place to see congestion, The place it most probably lies is at the handover points, or is a bottleneck within plusnets network including their DPI kit,

Of course that Plusnet have as many WBMC shared customers as every other ISP put together may contribute to that perception.

As far as congestion on the BT Wholesale core goes the issue I had earlier in the year wasn't my exchange, it was deeper into the network on a metro node, and of course there's this.

MR-DH isn't an exchange, it's the BT Wholesale POP located in Dial House, Salford. I'd call congestion out of a POP core congestion.

Previous to this there was congestion affecting multiple exchanges in the South Wales / South West England region.

BT Wholesale do seem to be struggling to keep their network in shape right now.

[re: MrSaffron] [link to this post]
 
For me 2014 was mostly ok, only occasional issues solved by a single ppp session hop.

Since dec 2014 the current issues started becoming apparent. In december initially it was a small drop of download throughput and nothing was affected, netflix etc.

Then in january it suddenly escalated and upload also started been affected, I also started to need multiple ppp session hops to recover performance. In addition during 2015 the peak time on tbb graphs started getting worse after a big improvement in q3/q4 2014.

On multiple occasions I have not noticed by doing speedtests but by services suffering e.g. iplayer stuttering and taking minutes to buffer 10 seconds of content, netflix stuck on SD, youtube taking ages to buffer etc. Everytime these issues occured I was always able to resolve by hopping the ppp session. Also speedtests were slow on tbb half the time upload speeds were also affected.

Then during march I managed to find a good endpoint (or good bTw routing if thats the issue) and performance was solid for a number of weeks, I even started to wonder if something had been fixed. Then last week I by mistake hopped my ppp session and BAM problem was back.

I thought I found the good routing/endpoint again after approx 10 hops one night bu tthe problem was back the next night, then after another 20-30 hops I found good performance again and I have sat there since.

In my case plusnet confirmed my SVLAN has blue status. I have also 'always' been able to recover performance by hopping even tho it now needs much more hops to do this as if the problem is getting worse.

I do think igniotion has a partially valid point when he says plusnet are within their rights to have network saturation, however where I think he is wrong is they should be open about it, if their equipment is the source of the problems then they should say so and make it clear the current performance is now the norm for plusnet. As jelv has pointed out multiple pages of the website say expected performance at peak is line speed, and it also should be made clear plusnet have stated multiple times an advantage of using their servise is their QoS system helps the user at the line level, but of course if the line cannot reach line speed then plusnet's QoS doesnt work as it relies on the line been able to reach line speed, not to mention that plusnet staff have stated multiple times in normal situations their network will not be the point of congestion.

Aside from marketing reasons I suspect a reason why they are not been open is the new ASA rules, a isp selling unlimited usage can only do moderate throttling, and deliberate congestion can be seen as a form of throttling. So it could be a plausible deniability game.

Every consumer ISP has to have deliberate congestion, i.e. NO isp can afford to sell consumer services if it has NOT sold a lot more connections than capacity it actually has.

As far as I recall nothing that outlaws congestion from the ASA rules, will only get sticky if different types of traffic are behaving differently, but even then ASA is useless because a video CDN on an ISP network may run perfectly but an external service be slow due to lack of peering links. The ASA ruling is very very simplistic and not a law set in stone.

Have to be cautious there and ensure the difference between contention and congestion is made clear.

I would recommend those confused to check the AAISP page.

It is possible to manage a contended network and ensure it doesn't hit congestion and hence has no visible contention and appears to be uncontended.

Extremely debatable whether it's possible at Plusnet's price points though! Those guys will definitely be hoping their mass-market status dilutes their average usage per customer strongly. If they were at the kind of levels Virgin Media have their network would definitely be melting down.

Not experienced any problems on Plusnet, Thinkbroadband Speed Test was 73.15Mbps down 18.15 up the other day, so would definitely say no meltdown from what I can see on my connection. Admittedly it is a Business package though so may vary slightly if traffic management is coming in to effect, but again never really experienced that in over a year being with Plusnet.

I've certainly had significant problems all day Saturday, Sunday, Monday and Tuesday. I had been running ping traces and had raised the issue with PlusNet during Sunday. In the early hours of Wednesday morning I became fed up with the situation and decided to go for a reboot. Since that point I have had no problems whatsoever. I have run a ping trace throughout the night and all day today and there has not been one single issue.

The server I was connected to from Saturday to Tuesday was lo0.11.central11.pcl-bng04.plus.net [195.166.130.178].
I am now connected to lo0-central10.ptw-ag02.plus.net [195.166.128.196] and the difference is unbelievable.

Mine was seemingly only getting about 30 - 40Mbit/s just now (On an 80Mbit/s sync) but then again I've been playing with different routers over the last couple days so it's quite possible it was the router I have on the line at the moment.

[re: MrSaffron] [link to this post]
 
I see no problem generally: My SamKnows box shows no variance in download speeds, upload speeds, or latency during peak hours compared with off-peak hours. The new tests for video show identical performance 24x7 for Netflix and iPlayer too.

Because that runs 24x7, it has many more results than I see from manual tests, and it is properly wired to the router.

But when I do run some manual tests, I can see some issues with the single-thread test. Sometimes. But my desktop isn't connected perfectly, so the issues could be my LAN.

Everything I read in the previous threads suggested that *something* was happening, and that it appeared to be restricted to some segments of the backhaul pipes. But the issue never seemed to hit many people at a time, so it is hard to say what is going on. It certainly wasn't enough to say that PN was systematically congested.

It wouldn't surprise me if PN's whizzo traffic-management edge routers are applying some different congestion avoidance techniques that lead to a controlled slowdown in places, rather than sudden packet loss.

Like many (most) others, I have been getting good speeds on all the tests I have made.
I tend to make speed tests during the day which seems to be less of a problem time, but Netflix/iPlayer have been working fine in the evening. Of course, that only uses a tiny proportion of the bandwidth.

On 40/20 connection, with potential on the line to go well above 70 down.

It probably was P/N but given i'd been playing with my network setup recently and didn't have time to test properly I don't want to say 100% that it's them as I can't be sure.

Current setup is as follows

Plusnet connects to a RB750 running routerOS, I was also playing with VRRP between it and an RB450G with the RB450G being the master, the default route on the RB450G points at the VM cable line so in order to force the traffic path to use plusnet I triggered a Mangle rule in the firewall to redirect traffic via an alternate routing table.

This means that the traffic path is RB450G > RB750 > Plusnet and also the RB750 isn't really an ideal router for an FTTC line as it's a little under powered for that (Depending on which features were being used).

I'd normally be using an EdgeRouter Lite but there seems to be a problem with the HW acceleration and the load-balancer, especially if you start using PBR to force certain traffic to a line and the device has a problem dealing with 150 + 80M and Policy routing connections in software routing mode.

Currently got a Linksys LRT224 on order, in a completely different class compared to the routers above, infact it's almost primitive in comparison but claims to do 900Mbit/s across the Nat and load balance, so it sounds like they've got the LB accelerated... Interestingly it seems to be a slower single core version of the CPU in the edgerouter (Cavium octeon)

It was either Tuesday or Wednesday I rang around 05:00 complaining about having video streaming from TWiT.tv regularly buffering when usually there was no problem, and speed down to about 2.5 or 3 Mbps instead of normally 10-11 Mbps on download.

Hope your fibre service was installed and you are seeing some benefit. My second line (with Post Office, so I have a dynamic IP too) went down on Friday and repair unlikely before Easter (at least they're replacing aluminium with copper, apparently).

What a difference a couple of hours makes - but this must be down to the gateway.
At 16:24hrs I got 37.4Mbps download and 7.2Mbps upload and 16ms latency (this is about my normal).
At 21:46hrs I got 19.3Mbps download and 3.5Mbps upload and 70ms latency.
Both above results on ptn-ag01 so I hopped and landed on pcl-bng01 and -
At 21:55hrs I got 38.04Mbps download and 7.24Mbps upload 16ms latency.

p.s. My BQM isn't pretty. - just realised that the link to BQM is 'live'. It wasn't pretty at the time.

So a peek at a massive thread elsewhere and a few people seeing single thread issues and signs on congestion on even multi-thread.

Is this widespread and thus ISP meltdown, or just the face of contention appearing on a few nodes for a few weeks on what is a consumer priced service?
I was seeing issues primarily on single-threaded TBB tests throughout January and early February but after BT carried out some work on my exchange things returned more or less to normal. I can still see a few issues Sunday and Monday but fairly minor.

We have lines from a few providers for test purposes and our PlusNet circuit is monitored like all the others on a CQM basis A&A style.

The PN connection does exhibit of late some severe increases in latency at times - especially 8pm-11pm, not every night, but becoming regular enough we had noticed it even though the line is only there for test purposes.

Certainly when we have used it, we've found streaming performance horrible of an evening compared to other test circuits, though this is by no means scientific testing.

If you look back to any of my posts just before that you will see my sync speeds leading up to it, which were a bit down from the 57Mbps or so I expect, due to interleaving that I caused. I was waiting for it to self-correct when this happened.

You can see my current line stats in an earlier reply to you. Fine as far as the exchange cabinet (/me idiot), but the wonderful current Openreach systems now require a bog standard engineer callout before they look any deeper.

I believe this is due to some congestion somewhere within BT network - I currently have the prioritised service on my line and everything feels better. Streaming doesnt buffer and Now TV doesnt downgrade quality, I also dont get slow downs at peak times. Not sure I want to continue paying the extra £9 a month for it though so contemplating next move.

i used to find that a bunch of gateways were always overloaded, but a few had great performance for much of the time. Now it seems like nearly every gateway is slow. The last few days have seen a nose dive in performance. Struggling to buffer some youtube videos at 720p, which is poor since I'm synced at 50/10.

I hate jumping from ISP to ISP, but I'm pretty sure we've been with Plusnet for ~18 months and it may be time to look elsewhere if things don't improve soon.

Is that the "pro" add on? I thought it was more than £9/m.

I think the problem reported here seems regional which would be BT wholesale rather than Plusnet.

I was trying to view the live video stream from twit.tv yesterday night, and that was repeatedly buffering, so in desperation, I used my mobile (tethering) and that was fine.

Connections to gateways may have been fine, DNS didn't seem to come into it (I regularly use alternatives and have them set up on my various systems), but the connection onwards from Plus.Net itself seemed to be duff, at least that's my interpretation.

I normally get 10-11 Mbps sync speed for downloads, and have had results in the 8+ Mbps on speedtest.net but currently seeing 2-3 Mbps on speedtest, with peaks perhaps instantaneously hitting 5 Mbps...

Roberto can correct me if I am wrong but it would depend on whether the other ISP has their own backhaul from your exchange or use BTw.

In reply to a post by narz:
If this is a local contention issue because all my neighbours took up Fibre, would jumping ISP's make a difference? i.e to BT.


It depends where the congestion is as to whether it will be common to another ISP.


There is a contended connection between your FTTx connection and the Openreach handover point - the cabinet to handover point connection for FTTC or the PON for FTTP. I would be surprised if this showed much visible congestion, but it is possible. If there is congestion here, it may well be common to all ISPs.


There is also a contended connection from the Openreach handover point to your ISP. For ISPs like Plusnet using BT Wholesale, this connection is the BT Wholesale network (common to all ISPs using BT Wholesale) and the connection from BT Wholesale to your ISP (unique to your ISP; large ISPs like Plusnet have multiple connections to BT Wholesale).

There is no commonality in this part of the connection between a BT Wholesale customer ISP and a non-BTw ISP (Sky, TalkTalk including TalkTalk Business customer ISPs, Zen at the increasing number of handover points where they have presence). My Zen connection goes over Zen backhaul, so there is no commonality between Zen and a BTw customer ISP from the handover point onwards (towards the ISP's core network and ultimately the Internet).


I hope that makes sense. In pseudo-diagramatic form:

FTTC customer <-- [non-contended] --> cabinet <-- [contended] --> BT Openreach handover point <-- [potentially contended against other ISPs using the same backhaul] --> ISP core network

See updated sig.

Problem was I was sync'ed to the cabinet but Plusnet didn't see me trying to log in at the radius servers.

Engineer booked for 1-6pm, arrived 1:18. Lots of tests. He was able to run the BT Test 2 or 3, I forget which, using his JDSU, and that worked. Tried a replacement modem and Bingo!

Except the JDSU was getting about 49Mbps sync frown. As did the new modem from what the BTW speed test showed for the IP profile. A small piece of kit he had said the HG612's firmware was out of date but he was scrolling like mad. He said it said to turn it off then on again to update. Which he did, wit o improvement. Hmmm.

Anyway, 2pm he was out of the door, so I flashed in the unlocked stuff and here we are smile.

Best speed ever, (barring a freak that ended up with heavy interleaving), including the initial installation as fourth on the cabinet.

BQMs won't be showing yet, I'm logged in on my non-IPv6 account, and in a rush to do something else, then put my ASUS router back on instead of the Plusnet Technicolor.

If it was our speed test at fault then it would affect everyone equally.

PlusNet are free to talk to us and can even do things purchase managed tester that can be placed on the internal network to help diagnose at a point closer to the consumer. Various other options are also available in terms of custom test solutions.

Because our tester is more honest in providing scales and data it generally allows people to see a lot more information, when other testers may smooth over some dips to give people a warm fuzzy feeling.

I have - sort of - been following that thread and as far as I can tell no member of Plusnet Staff has suggested that.
It was a couple of customers and the reason Plusnet are now following it up is to try to get a better handle on why the TBB Speedtester shows such odd results and, perhaps allow them to get a better handle on the cause of the problem

BT PT test result BT PT TAP3 TEST RESULT

I have no doubt some one will attempt to say this doesn't mean the capacity or distinct lack of it lies with plusnet , well if a tap3 test wich is testing BTW's network is providing a better result allthough not perfect as it should be around 74-75mbps it's sub 70mbps but a dam sight higher than the sub 10mbps result when on plusnets network

So yes plusnet network is in meltdown and has been this way for a very long time

It does tranist via Level3 peering from Plusnet and Level 3 link's are probably always run at or near capacity, and have in the past produced some really cack handed routing to some other destinations so they do have the potential of causing issues , sorry to but in BTW

it seemed to start late last week when andy was talking about it on the plusnet forums. now I see traffic going over 3 transit providers before hitting the tbb network which wasnt the case 2 weeks ago.

The affect I am not sure if any at all, but I am curious if you know the reason why it isnt going via LINX.

Well, I finally solved my speed issues. A duff CAT5, which was leading me to get anywhere between 2-10Mb single thread performance and around 20-30Mb when downloading a torrent.

Funny how 1 cable can cause such a headache. frown

At least it forced me to update my pfsense and fix an obvious flaw in my network layout. *sigh*..

Not sure if this was always my issue or a combination of mine and plusnet. But everything is working at full speed once again on my end.
