The very slow page loads was a pain.

I don't believe they are segmented.

I suspect the issue will be somewhere between PN and the WMBC Shared handovers at Faraday/Colindale. This would make sense as you can reconnect on the same gateway, but end up on a different handover point or host link to that specific gateway.

Based on my own experience it would seem reasonable to imagine that the BT Wholesale network is somewhat stressed on a few levels.

The issues affecting me were not at the exchange level but a layer deeper into the network, at the metro node, and the fix, while it has kinda worked, was very much a sticking plaster solution.

BT Wholesale have an ongoing programme to upgrade hardware at exchange, metro and core level, and EBD links. With the Christmas bandwidth spike and other things I suspect demand has overtaken those programmes somewhat.

I just disconnected/reconnected and went from bng01 (11ms ping to bbc) to ag02 (16ms ping).
Disconnected/reconnected again, back on bng01 and 11ms.
Opposite from what AndyHCZ saw; but probably his conclusion it isn't the gateways is correct.

I've never had better than 11ms on PlusNet: still much better than the 18-20ms on Infinity 2.

I'm usually interleaved (winter rain effect) so get 21ms minimum ping to bbc on any gateway :-/

Well the distinct absence of similar complaints from customers from other ISP's that use the very same BTwholesale products , and the same back-haul as plusnet It to me would appear to be a problem that is isolated to plusnet customers (being the issues that are still persistent ) as there where some problems on bt's side that where limited to certain areas ,which for the time being appear resolved, as has been suggested the problem could well lie with where plusnet's network meets bt's network feed, ie some of plusnets endpoints become overwelmed at peak times

As to the reasons ,that isn't paramount (diplomacy eh) but resolving this ASAP and providing updates as to what the problem is and how long before it will be resolved

There are three bng01s. ptn, ptw and pcl.

On Apple, they've moved most of their distribution over to their own CDN network. It might be related or unrelated, but Apple have a fair bit of work to do to catch up with Akamai. I've yet to be able to get fast updates (and this includes with another ISP in a different country).

Always get fast Apple updates here. I just tested and got 72Mb/s average downloading iOS. I'm not on Plusnet or a foreign ISP, though.

Can you see where you're downloading from? Is it uklon5-vip-sx-002.aaplimg.com?

As per my original post, disconnecting and re-connecting resulted in full line speed for all protocols to all sites..

I tried about 10 downloads just now, they flipped between uklon5-vip-sx-001.aaplimg.com, uklon5-vip-sx-003.aaplimg.com and uklon5-vip-sx-005.aaplimg.com and all ran at 72-74Mb/s.
