I have been with AAISP for a couple of years in my present flat in East London. I'm on FTTC 80/40, and it has been excellent throughout. Very fast and consistent speeds at all times, and fantastic reliability.
Originally I was on 40/20 and when 80/40 became available, I requested the upgrade. Due to a fault of my own when ordering on AAISP's website, it was provisioned as ADSL instead of VDSL 80/40. AAISP were great in managing BT and getting everything fixed up.
I work mostly from home and have a lot of services running on my line - video conferences, VOIP phones, lots of ssh tunnelling, scping, and pushing git repos around. It's been handled without missing a beat.
One thing though - AAISP is not cheap. But you get what you pay for. I've just bought my first flat and was to switch to someone else (Xilo are presently rated slightly higher on ISPreview) but the more I think about it the more I want to stay with AA. It's just a great quality product with top-level service.
