Forbes, and many other, report that GMail had an outage. Now I hear vast parts, in particular the security and privacy fraction, of the social bubble start crying “the cloud ain’t a solution”. Self-Hosting has sure benefits over managed offerings. This attitude ignores the fact that managed hosting, and multi-tenant (cloud-) applications in particular have one huge benefit over single instance solutions. This foremost means economies of scale. Any moderately successful cloud solution can serve plenty of users, and at a large scale, set a much higher standard for operations and security than the self-hosted application could have.
So while Google was off, it’s still much better available than most hobbyist projects.
My POV.
