I managed to stay up last night to confirm this and indeed it's happening. I don't know why. Everything else on the site during this time works, including the old board and the main url http://thekittenboard.com
I am investigating but I don't have any idea. I will write support to see if they can help.
I did not have to log back in after this happened. Although, interestingly enough what appeared to have crashed this morning was the sessions database.
