I'm having the same issue on Xbone. Last night at 12:30cst I was kicked by a Hawk error code and I have not been able to play Destiny since. Called Xbox support and my internet provider and both say nothing has changed from their end. My bandwidth is fine, upload speed fine and download speed is fine. WTF is going on!!?? I can sign in, get to character select screen and then I get booted when trying to load into orbit
