OK, I was pretty paranoid when we got thrown out and a couple of things happened.
Maybe it is my paranoia and pure coincidence, but within a few days our server was crashed several times due to overload (in excess of 200 queries per sec or something) and was not able to be fully rectified and considerable script errors were encountered.
Eventually we upgraded and had additional security measures installed.
A DOS attack requires some knowledge and access to a network of computers to achieve. I had a bit of a search today and this was pretty informative:

At the same time I found out about Krystalls attack we were not able to access this board. Possibly something this end but Prof anything unusual in your logs?
Maybe my paranoia again. But, the reality is someone has to pretty well have it in for you to do this as what I can see it takes a lot of effort to achieve.
Unless Cindy has been taking masterclasses in the darkside it is not her. A couple of members in the GPWA are capable I guess.
Basically if several of you have been affected this way, get together and do a shortlist if you suspect this is GPWA related.
