hmmmm.. I just had a thought - for the past month or so, Ive been seeing some carp speeds. Because it co-incided with the problems with BNGs I at first thought it was a Plusnet issue.
However, Plusnet assured me that there was no bandwidth capacity issue on their pipes.. This is the response I got
As far as we're aware there's no congestion issues on our network, we put additional bandwidth in for iOS8 above and beyond what was needed so the network has plenty of spare bandwidth right now. Checking through the monitoring there's no packet loss or any interfaces that are maxed out anywhere on the network.
Looking at the quality reports I can see some packet loss showing on your SVLAN back to the exchange, it's up to 5% last night, that could easily be the cause of a drop to 30Mbps (graph attached for yesterday).
Over the past few weeks things have deteriorated further and each evening I routinely see speeds of circa 20Mbps. Ive not been monitoring it though as 1) I didnt see the point in getting stressed about something that BT would hopefully fix in their own time 2) I could still do most things I wanted to do as my upstream wasnt affected and there was sufficient bandwidth to stream, which is where the vast amount most of my download usage is.
However... if it is backhaul capacity.. I dont see any reason why they should need to switch off the DSLAM for an hour.. unless its to hook up newly blown fibre. In general if new capacity is installed it should be more of a software configuration.. as the SVLAN is the equivalent of an old VP.
Chrys havent you too been seeing some capacity issues at peak? Has that been sorted now?
I guess I shall find out tonight if my speeds have increased so we can rule that out or not
