On Monday 7 December 2015, Google Container Engine customers could not
create external load balancers for their services for a duration of 21
hours and 38 minutes. If your service or application was affected, we
apologize — this is not the level of quality and reliability we strive to
offer you, and we have taken and are taking immediate steps to improve the
platform’s performance and availability.
Earlier today, most Google users who use logged-in services like Gmail, Google+, Calendar and Documents found they were unable to access those services for approximately 25 minutes. For about 10 percent of users, the problem persisted for as much as 30 minutes longer. Whether the effect was brief or lasted the better part of an hour, please accept our apologies—we strive to make all of Google’s services available and fast for you, all the time, and we missed the mark today.
Renaming this bug as it really has nothing to do with GMail specifically. To clarify:
If you did a Google search between 6:30 a.m. PST and 7:25 a.m. PST this morning, you likely saw that the message “This site may harm your computer” accompanied each and every search result. This was clearly an error, and we are very sorry for the inconvenience caused to our users.
