Black Sheep is quite correct. Everyone thinks that with AA it is all about support, but that is not it for me. That seems to be an assumption, I would not want to be without all of AA’s many facilities: IPv6 which used to be a luxury, static IP address blocks for free so no NAT, excellent email, reverse DNS, 4G, VoIP, CQM and the incredible clueless control panel, the ability to change everything yourself and launch tests yourself without having to even ask cust serv, the integration between router manufacturer and ISP so there the buck stops, IP link bonding so you can use multiple lines as if they were one, 3G failover, instant notifications when a line goes down, the fact that you know individual staff names so it has a human scale, so many other features that I cannot even remember all of them. I use absolutely every one of the bells and whistles and absolutely love knowing what is going on and feeling in control, as well as not being treated like a moron.
Perhaps someone should do a tour of all the various facilities, but only if people would be interested. I am notorious for promoting AA anyway, but out of a genuine desire to offer people an alternative which might help them when they sound frustrated or which might tickle their techie tast buds. AA is absolutely hopeless at advertising or marketing and even this existing user finds it hard to find things some how as some information is not well linked to on their website.
Multi-line bonding is where it all started out. I can no longer put up with 2.5 Mbps ADSL2, especially the upstream, that is not enough for a business. The local incredibly unreliable long range wireless wan service with zero guarantees of throughput is not remotely an option either. There were very few who offer a service that delivers this fully , without qualifications and in both directions. I tried Zen and AA and AA won. I don't think Zen offered multi-line bonding.
