Resolved] Google is in the midst of a massive interruption affecting Gmail, Disk, and some third-party services

In recent hours, there have been widespread reports of outbreaks associated with multiple Google services, including Gmail, Disk, Nest, Analytics, and Calendar. In fact, almost all of Google's service auctions are potentially affected by current statuses listed on the G Suite Status Dashboard. The problem seems to be regional, but with anecdotal reports indicating that not everyone is affected.
The down detector's live map shows that the problem seems to be most concentrated on the US east coast, with some reports it may also affect Eastern Europe, although there are several (and fewer) reports that other areas may also be affected.

Google's Cloud Status Dashboard also reports an ongoing issue, which may indicate a major problem with Google's Cloud, and which will later affect third-party services that use it. The problem can also be linked to a level 3 outcome, which appears to overlap the timing. Level 3 is a massive, business-friendly, wholesale provider used by many cloud hosting services.
According to Down Detector's live charts, this outbreak looks at piles of Shopify's third-party services to Vimeo and Snapchat. The odds are that if you have trouble connecting to a site or service right now, it is related to this massive, ongoing outbreak.
If and when we learn more, we will make sure to tell you.
Anecdotal reports indicate that the problem is starting to resolve for many, and a few statements issued to Google's Cloud Status Dashboard state that the company has found the cause of the problem and expect to see it fixed soon – even though it has already been missed window for a promised 4 PM PT update.
G Suite Status Dashboard is now all green, and individual statements are issued for each of the services listed:
The problem with [Google’s services] should be solved. We apologize for the inconvenience and thank you for your patience and continued support. Make sure your system's reliability is top priority at Google, and we're making continuous improvements to make our systems better.
Graphs of reports for affected services on the Down Detector have also been leveled.
Update: YouTube is back and working again for the vast majority of people! If you still see a problem, it should be resolved soon. https://t.co/SEJPWyaeVO
