I came to AA looking for an ISP that gave me lots of flexibility and low latency. Specifically some static IPs, IPv6 etc which are just harder to find from domestic ISPs - I have my own kit and I'm just looking for connectivity.

They've been absolutely excellent any time I've needed to contact them, upgrades have been smooth and without issue. It just works and I've got a flexible, low-latency line. Not the cheapest, but I am not here for a cheap service. Also nice to have domestic support that knows what they're talking about, I used to dread calling for help when there was a line issue in the past.. having to walk through many "are you on wireless" questions.

Really happy with them, can't recommend them enough!
