Anyone else noted increased latency today 21/11/22?

I monitor three lines on the TBB ping monitor, all three of which are with different ISPs. All are showing a big increase in latency since around midday today. I am using one of the connections myself and I am certainly noticing the increased latency connecting to sites...

Anyone else?

My Broadband Ping

World Cup.

Yep.

My BQM on various circuits has been horrible since 1pm. Bang on.

Doh! I had not thought about that (I try and avoid football if I can)....
Thanks!

My download speed on FTTP dropped from 300Mbps to single digits from around 1pm, recovering now. On Aquiss, they apparently got a 'few reports'! https://ebilling.aquiss.net/serverstatus.php

It's a bit concerning if that's how TalkTalk's network reacts to such an event. Here's a TTB graph:

It's not good

Here's my IDNet FTTC BQM: My Broadband Ping

The bumps and spikes are me streaming other things, football isn't allowed through my router

Nothing to report here. BQM Link

As the saying goes... "pays your money, takes your choice"

No visible issues on my Virgin Media DOCSIS coax connection. (no more than usual!).

You had a build up around 13:00 ... my BT service had a real slow patch from just before 13:00 to 15:15 which tied in with the England match.

I would guess that it was being stream by a massive number of viewers.

Interesting to see what happens when Wales play at 19:00.

The large increase doesn't line up with the footie and anyway my backhaul is Zen not BT (although Zen has had its troubles recently ).

There might have been a millisecond or two that I can blame on the World Cup, I'm happy that the rest is down to me.

I'm also on IDNet FTTC. Much worse for me than you... no idea what backhaul I'm on though.

Are you sure ... The football kicked off at 13:00 which is just after yours ramped up the same as mine ... https://www.thinkbroadband.com/broadband/monitoring/... if it is not football what were you doing?

It does look as though someone make a routing changing after a while which cleared yours.

I thought all IDNet customers were on Zen these days, but could easily be wrong- it may just be all new ones and those who were there anyway. You'd have to ask support.

Like I said- streaming. Up to 3 HD channels simultaneously, and it looked just as I'd expect it to from experience.

I think it's supported by the sudden drop- within the resolution you can get from a BQM it aligns exactly with when I stopped (lunch was calling ).

My TTB graph - not as bad as the one in your post.

Virtual1 EAD. Packet loss a bit worrying. Connection however seemed fine. VPN tunnels were all good.

I'm on IDNet FTTC on a BTw backhaul.

Mine is only showing degradation in line with use today.

I've been at this address for 5 years... I'll ask them, would be interesting to know!

Looks like LINX Wales have plenty of spare capacity.....

In reply to a post by billford:

World Cup.

We have no view of the traffic on the private network peering arrangements - which I would presume would be handling as much if not more of streaming the traffic than the public IX's like LINX and LONAP

From one or two other comments I've seen around I'm beginning to wonder if it's all as simple as I thought it was

Think I'll wait for a few more England games and maybe reconsider.

Well, it's not showing on my BQM, but I'm not sure that proves anything

Not on mine either - not even a sniff .... so was teh earlier bad patch on many co-incidental?

I'm assuming it means that there aren't enough people streaming a Wales-USA match to trouble the servers, but I could be wrong

billford

They are all at home now watching it on ITV or S4C (for welsh speakers), The England match was being watched at work so streaming.

Good point, I hadn't thought about that!

BPM for a property in Wales.

My Gigaclear BPM is the usual thin line.

A map of Snowdonia?

Somehow VM seemed to be ok, my graph a bit worse than normal, but didnt look like anything fell over.

Disingenuous, that is nothing to do with today's events. Looks like a poor connection where someone started using it at 9.10AM.

What is it ADSL?

A Darned Slow Line.

The BQM for my Talktalk line didn't even flicker.

There's reports of issues on BTW, TTB, Sky, Vodafone, etc. Even AAISP were not immune to throughput issues during the England game.

It's not concerning and it isn't anything to do with Talktalk alone.
Usage peak records were broken all over the place.

It is a 40Mbs VDSL connection. Attainable Net Data Rate: 44.336 Mbps

There was no one at the property. The problem continued to about 2 am and then restarted at about 11 am today.

In reply to a post by Michael_Chare:

No it isn't.

It could be the BTW estimate for the line's best possible, but would need to be on a 55Mbps or 80Mbps connection to attain it.

Edit: By the way, VDSL has never been offered in the UK so far as I know. FTTC delivers VDSL2 and always did.

The Zyxel VMG3925-B10C says " VDSL WAN Rx:40000 Tx:7330 (Kbps)"

I pay for a 40/10 service. I get all the 40 but not all the 10. Strangely since the line to the cabinet the max attainable download connection speed has reduced as the line is probably a little longer but the upload speed as increased from 6Mbps to 7.33 Mbps.

My post gave you two options. It could not be a 40Mbps connection and have a max attainable, (that means throughput) of over 44Mbps.

As you have confirmed it is a 40Mbps then the true max attainable is below 40Mbps.

If the max attainable as shown by the router is/was 44.336Mbps then it is either a higher speed line or by playing with router settings (not recommended on FTTC) you may be able to get closer to 40Mbps actual connection speed.

Edit: Just remembered, the BTW estimates are only in round Mbps, so you must be getting the max attainable from the router.

Edited by pluralist (Tue 22-Nov-22 15:14:58)

I would suggest that it is the Max attainable speed reported by the modem/router which is not an actual speed but a value calculated by the modem based on some unknown algorithm which can and often does show a speed above the maximum sync speed for the line.

My HG612 shows 80.908Mbps with a sync of 79.999Mbps at the moment.

Yes . I edited my post a few minutes before yours. Along with removing an associated comment.

I was having memory fade as it's a long time since I was in a conversation about attainable speeds. The conversation hadn't been anything to do with router stats until then. Nor speed .

I'd also misread (multiple times) kitcat's question "What is it ADSL?" My brain registered "What is ADSL?" Which I did think a weird one referring to some typo somewhere by Michael, as kitcat knows a lot of stuff. That's what caused my earlier alternative meaning of the acronym.

Remembering hazily a bit more about attainable speed. It's basically constantly varying inversely with the difference between the default noise margin (SNRM but often wrongly referred to as SNR) set for the line and the actual margin at the time.

It also ties in with the sync-time speed difference between 3, 4, 5, 6dB margin settings.

If you sync'ed at a noisy time then when the noise goes away (SNRM rising) the attainable shoots up. Re-syncing at a non-noisy time adds to sync speed by about half the difference between the high attainable and the resulting attainable. but an immediate second re-sync to gain more after that tends not to help. It all depends on how the SNRM is varying.
