I'm seeing extremely frequent server disconnects on my realm just today. I've been idling at various farms successfully for several weeks and just today I'm getting extremely frequent interrupted "server disconnected" messages as well as frequent timeouts where chests or villagers are unresponsive. 

I've started a ping on a nearby computer while connected via my ipad and the pings never drop so I think I can rule out any network issues on my end.

Please let me know what other information I can provide.
