In an extreme case of irony, according to a Google employee, the outage was so severe that it also took down internal tools Google engineers were using to communicate among each other about the outage, making recovery efforts even more difficult.
"It's disrupting everything, including unfortunately the tooling we usually use to communicate across the company about outages."
The networking issue appears to be related to an outage at Level 3, an US-based ISP that provides connectivity and various other services to Google data centers.
In January, a similar Level 3 outage caused authentication services to go down for all Microsoft cloud services, with the most impacted being Office 365, Dynamics 365, and Azure Government Cloud.
Google Cloud Platform services have been down for at least two hours, at the time of writing. Users in North America are being impacted the most, although some European users also reported scarce problems.
UPDATE: Google has resolved this issue at 17:00 PT, four hours after it started. The company promised to publish a detailed post-mortem report on the outage.
