I'm pretty sure there is. Speedtest net, Speedtest.bbmax.co.uk and one or two others all show me my correct download speed, 60mbps (even up to 67mbps) and 2.9mbps upload speed for my 60mb connection. But thinkbroadband java and flash tests show me anywhere between 6mbps and 10mbps sec down, and 1.8 to 2.9mbps up. So it pretty much gets the upload part right.
Doing the tests right now for instance, they're currently showing me these low download speeds consistently, while the other sites are currently still showing me the high speeds. I'm not worried about my speeds because I know I'm getting my 60mb, but just curious if others have noticed this from thinkbroadband. Perhaps it's outdated and not optimally configured for high speed fibre optic?

I raised this before a long time ago and I think the answer wasn't the issue with TBB, but with the peering between VM and TBB.
As for it not being able to hand high speed fibre optic...

Ask yourself how many other sites are therefore slow? Is it only the big speedtest sites that Virgin Media are able to connect to quickly ?

There were some routing issues with TBB today from about 16:00 - 18:00.
I noticed that the forum was slow for me around dinner time but a speedtest then was spot on.
During my time on 50Mbps I never saw much over 30Mbps from TBB although speedtest.net showed 50 all the time. Genuine differences as shown on my Tomato firmware router bandwidth charts. Never did get to the bottom of it as plenty of others saw the full 50. Strange stuff.

|

There was a fair few issues that were nothing to do with thinkbrioadband today on the internet.
Also http://www.thinkbroadband.com/news/5260-virgin-media... points to something we have shown time after time to Virgin, seems they may be taking notice now it has got this bad with spotify.
Speedtest.net can actually still give a good result even with stalls.
Also 67 Mbps from a 60 Mbps connection - does that not sound a little high to people?

@pete thomson, interesting video, thanks. I'd actually forgotten that one of my speed tests last friday, (the day the engineer installed the superhub and switched over from 10mb to 60mb), was a thinkbroadband test, giving me 59.56 Mbps. Doh! So, yeah, guess it does work. Not sure then why it's currently giving me very low speed readings. Here's three screenshots from last friday of different speed tests I did within a few seconds of each other.

I get terrible results via sky broadband on here too
Everything else is fine. Never had a download below 3 mb/s on my 40mbps sky package
TBB reports as low as 5 mbps for me... I've given up trusting it.

Speedtest.net can actually still give a good result even with stalls.
It is more generous to the ISP than the TBB test which just gives a flat average I believe. Speedtest.net document their methodology here - https://support.speedtest.net/entries/20862782-how-d...
When I checked what was happening on the connection using the Tomato firmware bandwidth graphing is was very clear that both TBB and Speedtest.net were accurately reporting the results and for some reason (probably VM peering) TBB was way way down on speed. I'm sure the TBB test gives accurate results and have no reason to doubt that it has sufficient bandwith to test VM connections - it's just that some VM connections don't show their full potential with it while others do.
VM does have problems - some severe local congestion issues and peering problems that only affect some routes.

"some severe local congestion issues and peering problems that only affect some routes"
Seb has spent a few hours testing, and reporting this to Virgin Media, since we run our network we can change routing temporarily

Not quite sure what you meant by that but I can say that I just got an email from the Openreach bloke looking into the data error preventing me from ordering Infinity and he said he'd fixed it. (Sent 20:19 and there was one last night from same bloke apologising for the delay sent at 22:36 ????). Quick check shows I can order Infinity now so I'll be doing so tomorrow morning and then VM's peering and local congestion problems will be of zero concern to me. One very happy bunny
|
|
|
It meant that we have told Virgin Media about seeing congestion problems on at least one peering link for over a year

Doesn't surprise me. My 50Mbps went right down the tubes to sometimes only deliver 5Mbps shortly after they started selling the ridiculous 100/10 unlimited on local pipes of 200/18 total capacity for 200+ users. When I complained I was given a fix date several months away so I downgraded to 10Mbps and resolved to leave at the earliest opportunity. That's now and as soon as my Infinity is up and running VM will be cancelled and I'll never be tempted by their marketing hype ever again. When they're good they're very very good but when they are bad (which is quite widespread now) they are horrid.

TBB's speedtest is consistently slow / incorrect. You are best doing what the majority of the world does, ignoring it and/or considering it irrelevant.

I was upgraded via the Superhub [ and a very nice Virgin technician ] on Wednesday to 60Meg
He left after my first TBB Test on Wed. which showed above 40 . Later that day and on Thursday tests were showing 55Meg up and 2.8 down
Since then TBB has rarely gone above 20 but Speedtest.net has varied enormously anything from 15 to 60 , uploads are consistently 2.8

It is rare that I get a bad speed test from TBB. It seems to affect higher rate users from what I've seen.
I went from 10Mb to 20Mb a few weeks ago and I do regular tests, they are all similar to

If its slow on VM but works on other ISPs and company fast connections (ie, 500mbps+) then there is something wrong with VM. Congestion is likely.

My VM cable line has just been upgraded from 10 Mbps (in practice, 9.4 Mbps at quiet times) to 20 Mbps, with the same old Webstar modem, and speed test results have varied in form and number.
Whereas the TBB Flash test on the 10 Mbps line used to show downloads being 'flat', usually at 9.4 Mbps throughout the test, now the speedometer needle varies wildly from about 20 Mbps down to about 5 Mbps, averaging out at 13-14 Mbps.
Speedtest.net, however, shows the download speed fairly consistently being about 19-20 Mbps (probably a little too high). Download speed for both programs is 1.07-1.1 Mbps (what should it actually be?).
I've always warned myself off speedtest.net, which used to give ludicrous results like 34.4 Mbps download speed on the 10 Mbps line when I had the firewall in Kaspersky Internet Security enabled, but now it seems to be the more accurate/consistent measurement program.

You are bearing out what I have been saying for some long time.
I used to use both TBB test [ not the flash one] and Speedtest.net and found huge differences between them - TBB was always almost half the speed of Speedtest.net
Recently I upped to 60 Meg - first week both speed tests showed anything between 55 and 60 , then TBB dropped to about 20 or less  while speediest.net continued to show me at 50 +
This last week TBB is again showing me at 50+ [ so is Speedtest.net ]
Don't understand it - but that's my experience.
Cable is into the house but thereafter I'm connected wirelessly

Same here, I just gave up on the TBB speedtest.

And as we have said if an an ISP wants to run one of its peering links hot/congested then that is their choice.

So how can this be changed? Are Virgin Media aware of the problem?

The test isn't unreliable. It is reliably reporting the speed that VM can deliver over the link being used to access TBB.
I'll freely admit that I've gone through this exact same thought process some time back and blamed TBB (search the forum). I was wrong as later experience has proved.
If you want to know what your local link can deliver then many Speedtest.net testers are on decent peering (I suspect that this is no accident).
|
|
|
Yes we have told Virgin Media, then over a year later they came out and talked about Spotify peering issues.
What to do, VM improve peering, they could peer direct with us if they wanted.

I should point out that our network (we run our own network) has a lot of great peers, and we have a link that we can force traffic over, but it would cost us so much to do that, that we would vanish pretty quickly.
Even if we force different routing, that link leaving VM will still be congested, and other services using it are affected. One reason for doing this may be that stuff VM consider less critical goes this route.

Thanks for the information.
|
|
|
|
Then should there not be a warning for Virgin Media cable customers, that TBB results for line speeds of 20 Mbps and above are likely to be "unreliable"?
|
|
|
|
If TBB published the fact that VM users wouldn't see their headline speeds and the reasoin why (poor VM peering) I suspect they'd be hearing from VM lawyers PDQ.
The test isn't unreliable - as I said before it is showing exactly the speeds a VM customer can achieve to the tester - plus any other sites on the same peering link.

Well the old problem is back again
4 tests done within 10 mins
1) TBB - 15 Meg down 2.8 up
2) Broadband Max - 53 Meg down 2.8Meg up
3) Speedtest.net - 61 Meg down 2.7 up
4) TBB - 14 Meg down 2.8 up
5) TBB Flash -- 12 meg down 2+ up

So look at the routing out of the ISP and you'll probably find different routes.
Wonder how many other sites and services are on this congested link, perhaps Spotify was.

The first couple of hops are your router to your CMTS. Then there is some bouncing around within the VM network. Hop 9 shows the first router outside of VM and LINX is part of the name so that is who their peering partner is on the route to TBB
Speedtest.net goes via packetexchange and it looks like they peer directly with the BBC

The actual ping times and amount of variation in them suggest to me that your local network segment may well be suffering quite high congestion.
Hop 9 shows that it is still LINX peering.

Thanks for the explanation - I actually understood that 
It does seem to run in cycles of , according to TBB decent [ i.e. pretty near Max ] download speed to very low speeds . I used to put that down to kids on holidays - but there's no real correlation with that.

Set up a TBB monitor...
http://www.thinkbroadband.com/ping/monitors.html
This is mine which is actually pretty good for cable...
My Broadband Ping
In a congested area you'll see more blue (average ping) a lot of yellow (jitter) and when bad some red (packet loss) at the top. Solid red lines just mean the connection was down for some reason - in my case today because I'd powered it down to tidy the cabling - I'd ordered Infinity but Openreach did a no-show yesterday (apparently quite common - the BT community board is full of complaints about them) so I've cancelled it and given VM another chance as it actually does look reasonable now to me and I'm not going to deal with a company that can't even be bothered to install their product on the agreed date - http://www.idontbelieveit.me.uk/openreach-the-unacco...

You think that's good? Have a look at this: My Pings
I think I may be the only house using 100Mb in my area, which is surprising since I live in the capital of Essex.
I also have a teen caning the connection for gaming/downloading/sharing 24/7 now that his GCSEs are all done.

So my results don't look good? 
My Broadband Ping

Post up your modem stats - that amount of packet loss looks like a fault to me - have you complained?
I deleted my old graph posted above as I got a Superhub for my upgrade to 60Mbps and obviously the IP changed.
This is today's on the Superhub - My Broadband Ping I gave it a bit of a hammering late on Thursday which will still show just past midnight when this one finalises to just show 29th.

I've not bothered complaining to VM yet as I recognise that my time on docsis1 is coming to an end -- shame really as until recently I've always had great speeds from my Ambit 256 on 20Mb.
I'm one of those weird customers who'd rather pay a few quid more a month for a reliable 20Mb connection than an over-contended 60Mb one with a dodgy modem.
It's years since I checked the power levels but nothing screams 'fault' to me -- can you spot anything?

They look pretty much spot on to me. I was expecting to see a poor SNR or high upstream power which could both lead to uncorrectable CRCs and probably show as packet loss.
I started on 20Mbps then upgraded to 50Mbps. I was far from impressed with the Superhub and eventually got it swapped out for a VMNG300 modem. Speeds were fine until just after they launched the 100Mbps unlimited service and then things got bad. I downgraded to 10Mbps because that's about all it was delivering a lot of the time.
I was going to take Infinity but got messed around by Openreach so upgraded with VM instead - 60Mbps for £2.50 a month more than 10Mbps (£25 for stand alone broadband). I'm again on a Superhub but at least now they support modem mode if it drives me crazy.
My area has improved too and I do see 60Mbps - at least I have when I checked but of course I've only been on it a day. Even if it only delivered 10 the extra allowances before STM kick in are worth £2.50

I suspect it's time I make the leap to 60Mb and get a tech to check the levels once upgraded.
Thanks for taking a look at my stats.

Setup the TBB ping monitor I pointed to a few post back. The chances are your problem is caused by congestion.
IMO the BBMax speedtest doesn't transfer enough data for a reliable test on anything above ADSL speeds
FWIW I just ran a TBB speedtest. I'm on 60/3

slight problem - I'm a mac only house - the PC Lappy is only for my daughter when she comes to visit .

The TBB monitor doesn't run on your PC or Mac at all - it's an online service. All you need to use it is a router that will respond to pings on the WAN (most will but it's sometimes a setup option) and a browser to view the chart.

My speed of 10 minutes ago

problem with the speed test on TB it some times does not pick an random sample size that is big enough so when it avg the speed from start to end it tends to be incorrect (its ok for ADSL lines as most of the times its less then 5mb on ADSL its sample size is norm good)
the BQM is good tool to use as it can see how congested the line is and any packet loss if that's happening (packet loss is very bad and can have an big affect on the use of the internet in general)

sure that's not the wireless router doing all that, as your min-avg-max are all ok (still could be an cable modem issue or cable line issue)

Random?
We do not pick random sizes for the data transfer, and I've been able to test much faster than Virgin Media connections fine (see >700Mbps)
How much data transfer are you seeing on tests? Generally I saw smaller payloads from the Ookla systems than our own.

in the past randomly it picks speed tests below 10mb (or 2mb as just happened) that is to low for 50mb + connections as some times it does not get the speed right (i can see in task manager its flat lineing the connection when it reports incorrect results)
i did the flash speed test as well 1 of them completed the download test in less then 1 second

So you are saying it picks a 2MB or 10MB file to download?
Care to share this task manager graph? Does the flat line agree with the speed we report? If yes, then you may just be suffering a hot peering link from Virgin Media.

I was shocked earlier on. On BBMax I often get 67Mb for my 60Mb connection. But tonight I got 75Mb! How am I getting that speed when it's 25% more than I'm supposed to get, and is it accurate? BBMAx is always the one that gives me the highest speeds. Meanwhile, I'm getting differing speeds elsewhere. TB giving me 57Mb java and 55Mb flash. Speed test.net gives me 62Mb on average but is currently fluctuating between 56Mb and 62Mb. http://www.speedtester.bt.com is giving me a consistent 66 to 67Mb. I've no idea why they all vary so much but I wonder what I'm really getting and which is the true speed tester.
I have another question. VM engineer came to my house on saturday and fitted a 10 dB forward path attenuator as my power levels were over 11 dBmV and are now down to 0. I asked him the benefit of this and he said it would ensure my download speeds never go below 60Mb. Well apparently not as I'm still seeing sub 60's, albeit not very much. So, is he talking rubbish?

Our current testers use 1024 rather than 1000 for the maths, so tend to under read, and we show life time average, rather than a peak speed.
We plan to show both figures in the future, so that people can see what their burst speed and sustained speeds are like.
In short most of the testers are accurate, just that they may be showing different figures due to different test methodologies.

my vm download speed has now gone back to between 100mbs and 90mbs since the cable upgrade.
