The last two days was unreachable due to Database errors, couldnt connect at all to it.
The forum does send me error emails. All were related to a certain IP adres and the same error: too many connections.
I was able to trace the IP address and found out that is was leading to some google wannabe. He wrote a pretty agressive spider ( which was the cause of my site being unreachable for two days.

only after i was able to put on the pages (which was hard since my CSS + headers are in the Database) the site became more stable again.
