BT Infinity Upload Speed Suddenly Very Slow

Have enjoyed BT Infinity 2 for 6 weeks now with download speed of 76mbps and upload speed of 19mbps.

All of a sudden I notice the internet is much slower. But its not the download speed, which various tests say is still over 50mbps....but the upload speed which has suddenly fallen to 0.4mbps.

Have restarted the router several times and it makes no difference.

You too? Mine went down to between 10-15% of its usual speed just after 1AM and just after 8 AM it went down even further, often dropping below 5% and is at about 7% at the moment. In fact, it has just started jumping between 0 and 500KB and it just jumped to 1.9 MBps (almost back to normal). Perhaps they are getting it fixed at last. Though it took me about twenty minutes back and forth at around 2AM before they finally admitted that it seemed that there was network fault somewhere.

Yay, looks as if it might be fixed at last as my upload speed is now jumping around close to its usual max +/- a 100 KBPs or so..

Between their useless CS and TS I have already had more problems in 6 months with BT than I had in about 6 years with BE.

P.S. when it went pear shaped their online wholesale speed test site was telling me that my upload speed was at 13 MBps (still only 60% or so of what it should be) but that was only true when connected to their speedtest. I.e. their test site is prioritised, for on other sites that could handle even faster upload speeds than I have at max I was getting between 200 and 400 KBps, like you were.

Are you seeing any packet loss?

Started around 0030 last night. We were advised that BT have fixed the issue and we noticed that around 0915ish.

Thanks,

John

Unfortunately, I had let my ping test lapse and I was too busy to think about it at the time. I just switched over to my mobile to finish the backups I was doing. According to the BT CS person, she eventually admitted that the problem wasn't my end but that there was a network problem further down, as she put it. Which made sense, as their speed test appeared to be working relatively OK, for while it was low, about 60-65% of my usual upload speed, which is not that unusual for it, and showed relatively normal download speed, actual upload speeds to non BT sites was between 150 KBPs and 400 KBps. When I tested on your site just before 2 AM my download was close to normal but my upload was ~320 KBps with a burst speed of ~400 KBps. Or between 10 to 15% of my usual result.

As John posted just before this one, it came back at around 09:15, ironically just as I was replying to the OP.

Yes, I just had a router restart and afterwards a speed test said 70.88mbps download and 18.77mbps upload....which seems back to normal.

I had the same problem but it seems to have gone back to normal now.
Just look at the BBQM. This is the very reason I left Virgin so I hope its a one off.

There was packet loss for me

The thing I found strange, and what brought the issue to my attention, was that I was able to watch HD movies online no problem, but surfing through web sites was incredibly slow. Indeed it even took a long time to bring up the web page for the speed test here.

Web pages took forever for me as well. Was it only BT or was it all FTTC connections i wonder.

BT only I believe, and movies may stream if using different peering links or located on a CDN inside the BT network

Noticed it this morning, but has been fixed now.

anything to do with this?

BT oops

That's pretty - it would sell as an example of modern art .

Is that the link you intended? Or was it supposed to be to the description of the cause?
