The server running fakecharities.org has fallen over. Both the server chaps and I are trying to get the machine back up.
I am sure that it is entirely coincidental that the server did come under an attack a few weeks ago, and that a malicious script affecting Apache was found to be running on it last week.
I am working on migrating the database and am confident that we will be back up and running again within a few days.
UPDATE: fakecharities.org is back up, but I am working on a more secure fix.
