but what i'm not fine with is that my speeds go down to adsl levels, i've had 2mbits rather than the 13mbits i was getting on adsl2+ which makes no sense at all
and also why would this be happening in non peak hours?
in peak hours it's mostly been fine...
there has to be something going on? maybe lots running torrents over night?
anyway i think we need to investigate

Quote from: bluewhale bit odd how this is only happening on fttc though as i hadn't seen this on adsl2+
I think that's the key thing, from the exchange back to the Internet everything is exactly the same as ADSL2+, from our network's point of view it can't actually tell the difference between FTTC and ADSL2+ (except it might be a bit faster). Maybe there's lots of people in your area downloading overnight, there's only a certain amount of bandwidth available. BT don't cap the bandwidth but there are limits on how much can get through if you see the difference. The fibre from the cab to the exchange has a finite amount of capacity and same with the backhaul links so in theory it could all get full and slow things down. A drop in speed of a third is within the acceptable amounts for BT's tolerance.
I am feeding things back though and will let you know what I find out.

i've been dropping from 26mbits down to 1 or 2mbits which is way more than a third
personally i don't think a drop of a third is acceptable on the pro plan either, otherwise what am i paying for..

are you saying that between the hours of 11pm to 6am i can expect to get 1mbits as i have had regularly happen?
are you also sying that on pro i may well end up with the same service/throughput as on a cheaper package depending on who's on my exchange?

doesn't matter to me where along the pipe the issue is, i would have thought that's for plusnet to sort out
also so is that 10% of a day? an hour?

The 10% is the busiest 3 hours of the day, averaged across a week. So if in your area the busiest time was 7pm - 10pm (which is generally the case unless it's a business area) and you ran 20 speedtests across the week in that time (1 per hour across each day), to be considered a fault you would need to see 3 or more of the speedtests below 8Mbps.

Will BT ever be able to support that kind of broadband? _ I would have hoped now that the FTTC and FTTP were here, that we would get close, but it looks like BT have their own bottlenecks. Why does cable not suffer from that? Do they have their own backbone round the country that is fatter than BT?

Yesterday it was going on for midnight before things sped up again.

Those speeds are consistent with the ones I am seeing on mybroadbandspeed as well.
The BT Speedtester gave me a better result earlier (18 Mb/s) but all the web based ones, downloads, video stream etc are very slow tonight. If it's anything like last night once it gets close to midnight the speeds will jump.

@TonyC
I ran the speed testers after your post and was still getting low speeds. The BT one was the only one giving good speeds (Dave - is this prioritised?) I see your ping was high, although not as high as mine which was about 180ms at that time.
Video streaming on the 360 kept dropping down to the lowest quality setting, usually it is happy running in top quality even during peak hours.
Everything sped up for me again just before midnight.
