Last night my girlfriend and I were going through Prison of Elders 28, we got to Round 5, and were booted out of the servers and sent back to the main title screen with an error of I think 'Newt'. This was pretty aggravating since we made it to basically the last round and you can't resume. So we had to finally get logged back in and go through again. Just kind of a PITA when you make it that far. I've also seen reports of others getting the same only they were in the treasure room. Also, this morning when I hit 'A' to play Destiny it told me that the servers were unavailable, but then logged in. Not sure if there is some kind of load balanced hiccup or something there. Wanted to make aware.
