They noticed that some ssh sessions took 0.5 seconds too long under certain circumstances. 😲
Holy hell that’s good QA.
Don’t see why you’re being downvoted, the person in question who discovered this is a postgres maintainer employed by Microsoft.

What is additionally surprising is the breaches of Microsoft services in the last year. There is one every few weeks or so… And then they pick up a backdoor because login took 0.5 instead of 0.1s.
Anyway, his findings are amazing.
