Site down?

[Sh05]

Is anyone else having this problem. It comes up as a host error. I'm not sure this will post as when I try to post the error message comes up.
Who's attacking us again?!

Yes, I've noticed it happening specifically on Saturdays, at least three weeks in a row now.

The last 3 Saturdays for me have been rubbish, the site has been down and up again for hours at a time.
