It also can be our end; sometimes the system gets in a bit of a "wet blanket" mood and gets stuck.
@postalbo: I've given the system a swift kick in the backside, access should be fully restored shortly (your unsuspension was actually stuck, so it never fully processed).
@lhstitch: That more than likely is a cache issue as others have mentioned; clearing it should resolve the problem as I'm not seeing the suspension page on the co.uk domain.
