It’s not my network. I don’t have issues in any other games, streaming services, voice chats, whatever. With as many people experiencing this stuff, it can’t be just individual network issues. Bungie’s got to fix their stuff.

... nice 'pat' answer there. Not everything is client side -- my network works extremely well, but this has happened to me before and still does sometimes. You're playing several games fine and then for no reason you're booted out of a game before it even starts. Sometimes though it will let you back into the fight.
