I'm sorry to have to announce that there'll be another server move shortly. The good news for most users is that the DD server will be returning to the US with this move, which should improve response times for those users. The new host appears to have very good international connections and even the Aussie users will find it should be fairly swift still.
I don't know the exact date yet that the move will happen, and I'll try to give as much notice as possible. Please follow us on Twitter ( @deardiarynet ) for real time updates when the move happens.
Thanks for your patience everyone!
