Again, it’s not you, it’s Google.
Hangouts is currently down, though the apps status dashboard doesn’t reflect the situation.
Update 9:36AM: Google has updated their dashboard to show that there is a service interruption. They are “investigating reports of an issue with Google+ Hangouts” and “will provide more information shortly.”
Update 9:49AM: The Google Voice site is also completely down, returning a 502 error.
Update 10:03AM: Google Drive is struggling as well.
Update 10:38AM: Hangouts, Voice, and Drive are coming back up for some. Hangouts is still out for us in our Google Apps account. Google says they will have more info to share at 11:15AM.
Update 11:11AM: All back on our end. How are things for you?
Update 11:23AM: Scratch that, we are still having issues with Hangouts.
Update 11:29AM: Google had this to say on the situation – “Google+ Hangouts service has already been restored for some users, and we expect a resolution for all users in the near future. Please note this time frame is an estimate and may change.”
Update 12:27PM: Things seem to be good around here. Finally all good for you?
