Hmm, this seems like it's something that nay be happening specifically to you. Have you heard of any others that have had this happen? Also what console are you on?
I'm on PS3 and so far I haven't heard of it happening to anyone else. Could just be a bad connection to the server. (Not on my end as I've never had server issues with any other game I play, but who knows) I'll give it a couple weeks or so for them to get the servers a little more stable, and if it's still happening I'll contact Bungie and my ISP directly to try and figure it out.
