We must be lucky...
Like penguin slapper, I'm in Birmingham, and have had the cable service since it was first available here. It's been borked on only a very few occasions, and I must admit to feeling somewhat smug, occasionally. Usually, it "just works", as sold; I now have their 20Mb service, and that's what I get.
However, since they dropped newsgroup support, their "technical support" is useless, unless you win the lottery and get one of their UK-based staff.
