Site responding incredibly slowly

[Geraint]

I've been getting page not found messages, refreshes not refreshed, posts timing out and being lost and the like for the last half hour or so.

Yep, I've had that issue as well. It's gone now, though. Might have been my provider but who can tell.

I'm still having the problem, but it comes and goes.  Some sends respond quickly, others crawl, and still getting the occasional page not found error, but not as much.
