I guarantee Google Stadia is what's causing the server issues. Google's systems are constantly scanning game files for personal data. Whatcha wanna bet Google tripped security protocols in Bungie's servers? For the "right fighters" out there, this was merely a theory concocted in the absence of information. Nothing more, nothing less.
Nah, it had nothing to do with Stadia. It was in issue in our data center that affected all platforms. Our engineers worked hard all day yesterday to restore service. Sorry about any inconvenience while we worked on the fix.
