Moved to AAISP a couple of months ago. BQM in signature. Up until a month or so ago the BQM on Thinkbroadband was not good looking, but in response to a thread here it was picked up by AA and some changes were made. It appeared specific to the routing to Thinkbroadband, oddly didn't effect speed tests on TBB that went the same route. I mention this as if you look back over posts you might see references to poor looking BQM charts at TBB.
The higher speed packages are newish for AAISP, and so we connect via new (faster) Firebricks, and as I understand it these are kind of prototype boxes and have gone through a number of firmware updates improving performance, this means there have been a few scheduled overnight drops, and some minor teething problems, all transparently spoken about in their news section (https://www.aa.net.uk/etc/news/fb9000-lns-progress/) and on their status pages (https://aastatus.net/timeline-view.cgi). Of course these updates and issues are not unique to AAISP, the difference is AA don't hide them behind a service status page that constantly says "All systems currently operational" or immediately delete historic issues once they are resolved!
I've not noticed any regular congestion issues, there has been the odd time where there is what appears to be congestion, again this in the service status page and was it seems due to the new Firebricks running firmware not yet optimised for them. I would think some more boxes will get added to give more headroom once they can get them when supply issues ease.
Some sample speed tests (note my router has QoS enabled and various priority queues and so top speeds always fall a bit short than maximum obtainable to avoid buffer bloat) .
