There seems to be a Docs/Drive outage now. I'm experiencing it, and several on twitter seem to be as well, e.g. https://twitter.com/andrewrowland/status/740638173466873856 https://twitter.com/mikeMaher/status/740638453940031488 https://twitter.com/SkyOtic/status/740636169952735233 https://twitter.com/JamieGoswick/status/740636138814066688
I tried to submit http://downdetector.com/status/google-drive which has a bunch of those twitter links but it's apparently blacklisted.
