Title: Appaling speed tonight on TalkTalk
Post by: broadstairs on February 22, 2016, 08:51:39 PM
I was wondering why my download of a BBC1 program was taking so long. My download speed has dropped as low as 8mbps tonight on TT large with a sync at 64mbps. Anyone else seeing problems on the TT network tonight!

No problems here in The Cattery, Stuart. (Bury St Edmunds, Suffolk.)

But I do not have a FTTC based service.

P.s. I guess you actually mean 64 Mbps ?

Yes I always forget the capital M! I have down a speed of me test which shows 14.82 Mbps down and 12.31 Mbps up, the TT speed tester shows 36.2Mbps down and 18.8 Mbps up but I guess that is all within their network. Still not good enough as I should be getting at least 50Mbps I believe as I have been interleaved thanks to DLM some weeks go. Prior to that I was seeing a 72Mbps sync speed. A bit earlier tonight I saw just a tad over 8Mbps down speed on the speed of me tester  >:(

Hmm . . . That is a pretty poor result, even allowing for the fact that it is a TalkTalk service.  :(

You mention using the TT speed tester -- ever since the events of last October (2015) I have not been able to get that speed tester to work.

I just ran another (spped of me) test this morning and got 60.13Mbps down and 19.49Mbps up which tends to indicate a network issue somewhere. The TT speed tester has moved to http://www.supportal-test.co.uk/ (http://www.supportal-test.co.uk/) according to one of their OCEs on the community forum.

Title: TalkTalk throughput slow, line speed is OK
Post by: sheddyian on February 23, 2016, 10:14:30 PM
I wondered if anyone else here was having problems with TalkTalk speeds this evening?

ADSL2+ connection, been up for 20 days, synch speed of 20201 down, 1020 up.

Today I noticed some web pages taking a long time to load, some seemingly timing out.  (Possibly last night as well).

speedtest.net shows a throughput of 3.97Mbps down!  :o  The graph shows a peak at start of around 5Mbps, fluctuating up and down (but never very high) ultimately tailing off.  With my synch speed I'd expect throughput of around 16Mbps.

A reboot of the PC, the network switch and finally the router did not change anything.

After the reboot, I've now got a line speed of 20201 down, 1020 up, but a throughput of 3.63Mbps according to speedtest.net

It also seems that pings are a bit variable

ping to www.google.co.uk :
Timings pretty much 29-32 ms but 4 out of 32 timed out.

After the reboot I tried a few more, 1 out of 12 timed out, out of the 11 successful pings, 10 were around 29-32 ms as before, but one was 271ms.

Something isn't right :/

Anyone else on TalkTalk seeing this?  Any thoughts what might be up or what else I could try?

Yes see http://forum.kitz.co.uk/index.php/topic,17072.0.html (http://forum.kitz.co.uk/index.php/topic,17072.0.html) last night and tonight and I have fibre but was seeing very bad speeds, see also this thread on TT forum (http://www.talktalkmembers.com/t5/Superpowered-Fibre-Broadband/Fibre-large-connection-slows-down-unacceptably-in-evening/m-p/1872541#U1872541).

Ah, thanks!  I had a quick skim of posts on Kitz for something similar, but missed that.

I started a different thread in ignorance, but I'm seeing the same thing right now on the South Coast, on my ADSL2+ connection.  I half-noticed it last night I think.

Synch speed is just over 20Mbps but speedtest.net reports throughput of 3Mbps or less, and the graph fluctuates up and down as it tests.  (I would usually see around 16 - 17Mbps).

Pings are a typical 30ms, except that a few time out, and the occasional one is over 200ms.

I went to use the TalkTalk speed tester, and had a lot of problems finding it.  It now seems to be using the ookla one, with some added dialogue to ask your phone number.

I logged into "my account" on TalkTalk, and via the help pages, ended up at this worryingly anonymous looking site!
http://www.supportal-test.co.uk/ (http://www.supportal-test.co.uk/)

That too reports very similar and very slow speeds for me right now.

I've been running speed tests on Thinkbroadband, the TT site and Speed of Me, all give very different results in the evening with TT being the best but still well below what I expect for fibre with a 64Mbps sync, easrlier Speed of Me gave me about 5Mbps both up and down  :o :o Just a thought what is the first part of your IP address? Mine is 80.47...... if we are on a similar IP that could be the issue?

All fine on my end, but this sounds a lot like the time we had congestion at the exchange :-\

My graphs from the SamKnows Whitebox all shows good for me the past 48 hours.

Yes but that means 2 exchanges with severe problems, not impossible but not highly likely. Cold be a network issue if we are on similar IPs.

Ian I've added some comments in your other post. What is the first part of your IP? Mine is 80.47..... could be a network issue if we are on similar IPs. As I mentioned at around 6am today my speeds were what they should be 60Mbps down and 19Mbps up on Speed of Me test site, so it can be OK just not when it gets busy.

Also looking through the treads on the TT Community it seems others have issues as well.

I'm a very different ip, 78.144..

As I'm on ADSL2+ I wonder how much of the connectivity is shared, ie how likely is it there's a common fault affecting fibre and ADSL?

Ian
Title: Re: TalkTalk throughput slow, line speed is OK
Post by: sheddyian on February 23, 2016, 11:38:18 PM
Just to add that the problem seems to have gone away.  I've just re-run speedtest.net and now get

Down : 16.72Mbps
Up     : 0.90Mbps

Which is pretty much what I'd expect when it's working OK.

Will be interesting to see if it's a peak time congestion thing, or indeed if it comes back at all...

I replied with some stats in the other thread (very different ip) but also just now that the problem has gone away, I'm back to ~16Mbps down, which is what I'd expect.

For anyone interested in automatic speed logging via a Raspberry Pi, this article might be of interest
https://www.reddit.com/r/technology/comments/43fi39/i_set_up_my_raspberry_pi_to_automatically_tweet/ (https://www.reddit.com/r/technology/comments/43fi39/i_set_up_my_raspberry_pi_to_automatically_tweet/)

I was just tinkering with that (my Python is very basic, so I was struggling, but I did get it to work.
(I didn't want the twitter feature so just commented that out)

It also needs speedtest-cli which can be read about here http://www.raspberrypi-spy.co.uk/2015/03/measuring-internet-speed-in-python-using-speedtest-cli/ (http://www.raspberrypi-spy.co.uk/2015/03/measuring-internet-speed-in-python-using-speedtest-cli/)

The script on the reddit page seems to have a bug where the date format is saved in an odd format, ie 1456270028290.41 which makes no sense to me.

Anyway, I might have a go at modifying the code enough to just run every 30 mins or hourly and log the stats in a file so I can compare throughput over time.

OK that means the issue is probably further into their network. I believe that once your request hits their backbone there is little if any difference between ADSL and VDSL.

This morning my Speed of Me test shows a much more acceptable 51.36 Mbps down and 16.06Mbps up. This has to be some severe congestion in their network somewhere which builds up towards the late afternoon/evening. Hopefully I might see some response to my thread on their Community forum.

   A few weeks back congestion hit a number of TTB users.  It seems to have vanished now and all seems OK.  A characteristic was ping packet loss on TBB BQM tester.  see e.g.

   http://forums.thinkbroadband.com/fibre/4455594-ttb-speed-fluctuations.html?vc=1

   It may be worth running the TBB  BQM to see if that shows your issue.

Post by: broadstairs on February 24, 2016, 10:13:14 AM
I seem to remember that the BQM tester is problematic on a ZyXEL VMG8924 router and right now I dont have time to get it working. I'll wait and see what (if anything) I get on the TT forum.

Still no reply on the TT forum but I've been running some speed tests occasionally today and each time the results have been good, I suppose I should really wait till this evening for a true test.

Stuart

Post by: broadstairs on February 24, 2016, 05:42:38 PM
As usual fobbed off by TT, asked which router (as I dont use theirs) and asked for pings and traceroute to Google UK site. Not that I need help but their help page on how to do pings and traceroute has nothing for Linux on it  ::)

Spoke too soon bout speed, my downstream is now only just over 23Mbps.

When I had congestion on my exchange, my graphs were appalling - and the drop in speed substantial. See attached - peak time will be when you see if it was just a temporary issue.
Title: Re: Appaling speed tonight on TalkTalk
Post by: sheddyian on February 24, 2016, 09:48:45 PM
It's fine here for me tonight, seeing expected speeds of 16Mbps down, .90 up and pings around 15 ms.  So it may be that whatever is affecting you wasn't the same problem I saw yesterday.

I hadn't realised until today - even when the pings were consistent, they were twice what they are now - yesterday the reliable pings were around 30ms, today it's 15ms.

Well mine is still playing up during peak times. I'll wait and see what they say on my TT Community thread today.
