TPB merely changed servers It appears that TPB is merely having problems with their hosting. In any case, it should be back up for most people by now (at least the backup that they loaded).
They went from being hosted by Piratpartiet AS51040 to being hosted by SeriousTubes (AS51006).
SeriousTubes appears to be one of Piratpartiet's main suppliers of bandwidth, so it's not like it has moved very far...
Anybody having problems merely needs to refresh their DNS.
Only the thing is now it's not technically being hosted "inside Swedish parliament". Interesting...
