A message at [1] Faith Freedom (thanks to Norwegian Kafir):

The FFI forum is temporarily unavailable.

Someone probably gained admin privileges in the forum via a security vulnerability in phpBB. To prevent further damage, the script has been taken off-line.

The forum will be back when the extent of the damage has been determined and phpBB's holes fixed. Everything should be ready at 4 PM GMT, possibly sooner.

This is [2] not the first instance of this sort of thing.
