I've been weaseled twice in the past hour or so, then after the last one I got a 'Downloading Destiny Update' screen for two seconds and then boar when I tried to log back in.
I hope it's just a passing thing as it's been ages since I've gotten problematically frequent error codes, but.. just in case this going to be a thing I figured I ought to report it. I'll try again in a little bit and see if it does it again.
EDIT: After some research, it seems my ISP (Comcast/XFINITY) is experiencing some issues with DNS today. I double checked other games and they're DC'ing me as well.
