I have disconnects very often too. At least twice per hour, sometimes more. But one thing is strange - when I was at the Cutter's Cry dungeon - I have no disconnect. (When I came out - I had three every 20 minutes). I wish SE will fix it asap, otherwise I wish SE staff has diarrhea as often as I have disconnects from their servers.
Look at the screenshot below - it is clear that problems with disconnect arose at SE servers.
