The site has gone down a couple of times today. Lengths have varied.
I think I can expand on that a little, if it helps.
I've noticed a few times now in the last couple of days, it appears as though the site has partially frozen. I can refresh the main page successfully, but am completely unable to access any of the threads via the main page - they don't even appear to be attempting to load. However, if I click on a user who has made a recent post, I can pull up their profile, and view the post they made to the thread. Eventually, attempts to refresh the main page result in the server busy message. Then the site comes back and all seems to be well again.
What I know about databases will fit into a thimble, but it appears that certain methods of accessing the forum continue to work, while others are frozen.
Anyone else seeing the same behaviour?
