From this,

It sounds like they were/are using GitHub to host company-private source code, presumably of high-value.

While it's hard to know exactly the setup (e.g. maybe they are running their own instance of GitHub internally), this is your reminder that public clouds are not secure, no matter how much you pay the maintainers of said clouds.

Internal network compromise is of course always possible, but sheesh, it sounds like this list has lots of public cloud failures.
