That's worth knowing. Also, as a long-term subscriber to A&A for home/business I can recommend them as being very good as an ISP, too.
Their control panel is incredibly functional – containing detailed logs of pretty much everything. They also provide a lot of more technical line control options that you'd otherwise have to phone up and convince somebody to get changed.
We haven't had the pleasure of needing to phone them up yet, but from what I've read about them they're a technically very capable team.
I really can't recommend them enough. Sure, it's expensive, but a) I like the feeling that I'm contributing to things I agree with, and b) the people who work there deserve to earn a decent wage. Insofar as broadband has a "first class" product, they offer it.
