Completely justified reaction. A lot of the time tech companies and IT staff get shit for stuff that, in practice, can be really hard to detect before it happens. There are all kinds of issues that can arise in production that you just can’t test for.
But this… This has no justification. A issue this immediate, this widespread, would have instantly been caught with even the most basic of testing. The fact that it wasn’t raises massive questions about the safety and security of Crowdstrike’s internal processes.
