I'm still on 'ptn-ag01'
My TBB ping chart looks about the same as this time yesterday.
Pingtest to my usual fastest test server 'Xilo' was 42ms with 2ms jitter only half an hour ago, but is starting to creep up.

Although a traceroute to bbc.co.uk seems slower than I first had when I first joined, but still pretty much normal:

Can still get full speedtest results on most London servers, but the graph plot of progress is quite jagged whereas it is normally quite even.

iPlayer test results are much slower than I have ever seen before -

TBB ping graph looks worse than yesterday

My FTP connection just unexpectedly got "closed by host" while attempting to upload these pictures. That has NEVER happened before.
Youtube seems OK with no stalling or frame losses.
No buffering issues on iPlayer.
eBay page loading in multiple tabs seems to be OK, where this is usually the first symptom that I see.
I don't do any gaming so can't comment on that.

BT Speedtester results even worse:
Download speedachieved during the test was - 5.72 Mbps
For your connection, the acceptable range of speedsis 16 Mbps-65.89 Mbps .
Additional Information:
IP Profile for your line is - 65.89 Mbps
2. Upstream Test: -provides background information.
Upload Speed
9.99 Mbps
0 Mbps 20 Mbps
Max Achievable Speed
Upload speed achieved during the test was - 9.99Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps
ETA: Switching to gateway ptw-ag03 has got speeds back to more what they should be (around 60Mbps) with 30ms pings. Something about pcl-ag02 isn't right tonight.

When it becomes a problem for me is when I open many tabbed eBay pages, and I end up having to refresh each tab because the page hasn't loaded, but that isn't happening just now.

My speeds are well down:

and my ping graph is atrocious:

Tracerts seem to be 'okay', although a little slower than usual.

Initially on ptw-ag03. Whilst testing, I was disconnected and came back on pcl-ag02. No issues for me on that gateway.
It all seems very random - i.e. not affecting a particular gateway, or PN datacentre. I'm wondering if the problem might actually be in the BT wholesale network? Reconnecting PPPoE will force a new circuit through the network and my theory is that a lot of VPs might be running hot with the massive takeup in FTTC?
I'm in Slough, and tonight is the first time I've experienced this issue first-hand. Anyone else having issues in this area tonight?
EDIT: Seems like I had the opposite experience as tgheretford here.

Quote from: Barry I'm wondering if the problem might actually be in the BT wholesale network?
That was my conclusion yesterday when my pingtest results were better from foreign sites than anywhere in the UK.
If this was a Plusnet problem then all connections would be equally affected - whether UK or abroad.
If this is a BT issue then UK sites would be problematic, but international routes may be different - which is what I saw !
