Amusing, I do think the type of thing Tiscali has is good as their service status page. It doesn't list everything but it helps people know about what's going on.

I know there have been discussions about this in the past about who would be responsible for updating it etc. but looking at other hosts, it's generally provided as a standard service by most of them.
