If you were busy playing pointless word games . . .
 

. . . on the forum, you may have missed this:

A mail storage server has crashed. We're moving services to alternate servers and should be back shortly.

All services have been restored. Any delayed mail will be delivered shortly. Thank you for your patience!

Who cares???

Some of us.

Also...Fastmail have temporarily disabled account renames due to a bug. We're testing a fix and aim to have renames available again early next week. Aliases are the best alternative for now.
