I've always been curious about using AAISP: various friends have used them, and been ecstatic, and I knew Adrian vaguely at university. But the need wasn't pressing: the people I knew who were using AAISP had specialised requirements (VoIP, for example) and I was happy with O2's rebranded Be service, which worked well at my location and was relatively cheap. Native IPv6 would have been nice, but a Hurricane Electric tunnel worked well enough.
Then O2 decided to get out of being an ISP, and took Be down with them. So I switched. And my parents were in the same position, so I switched them as well. ::1 100GB for them, ::1 200GB for me. Not cheap, but not breaking the bank either.
The switchover was painless, and we were all up and running on the agreed date. The supplied Technicolour (Thompson) router didn't quite seem to cope with being connected to a second router with multiple interfaces each with its own /64 (AAISP provide a native /48) so I had an excuse to scratch my Mikrotik itch: because AAISP are run by grown-ups they were perfectly happy to give me support with a Mikrotik 2011 and a DSL 320B in place of their router, whereas O2 always needed me to plug in their router before they would do anything.
Performance is excellent. Support is astoundingly good (albeit office hours only): today I wanted Annex M set up and it was up and running within 20 minutes. There's extensive logging and graphing that you have access to, too, which means self-diagnosis for those with clue is easy.
I can't really fault them. They not cheap, but then that's not their target market. Good support, good network, good people.
