Gmail appears to be down with reports coming in from Europe, the U.S., Canada, India and beyond that Google’s email service is down. I am still seeing a green light on the App Status dashboard, but all of my emails that utilized the Google platform are down right now.
The error I’m seeing is a Temporary Error (500), which pretty much just indicates that it’s a temporary problem and doesn’t give a clue as to cause. Judging by the response on Twitter, however, the problem is currently affecting a huge number of users. Google+ is also down, although you’d be forgiven for not having noticed that sooner.
The Google+ outage also affects YouTube comments under the new system, which means those aren’t loading at all on videos, as well as Hangouts across the web and mobile. Users attempting to access Gmail via external clients using either POP or IMAP protocols also aren’t able to get through to their inboxes.
