Yeah I thought this might be the case. It's possibly a little pre-emptive unless there's a bunch of feddit.uk users who are causing trouble and it's just easier for them to do this, but it's a bit shit that we all lose access to one of the biggest instances because they can't reach our admin? They mention there's other instances too, I wonder which those are.
I had noticed that Tom has been very quiet recently, we could definitely see if he'd be open to allowing more admins when he's next around.
