UAN Servers went Poof

Hey guys,

Both the servers do not show up in my favourites any longer. Tried to addem again but it says they are already favourites. Checked my filter settings so they should appear. Dunno wtf happened but they went poof. Any help would be greatly appreciated.

its probably your filters...
turn off pure servers only

see if you can ping them
if not then check peerguardian if you have it or your firewall if any
