Apparently they have a "unexplained crashes must have an explanation determined" policy ever since there was a trend of uninvestigated unexplained crashes that were canaries in the mine for a security issue.

> But [the Cloudbleed sensitive information disclosure security incident] wasn’t the only consequence of the bug. Sometimes it could lead to an invalid memory read, causing the NGINX process to crash, and we had metrics showing these crashes in the weeks leading up to the discovery of Cloudbleed. So one of the measures we took to prevent such a problem happening again was to require that every crash be investigated in detail.

Since then, they have a "no crashes go uninvestigated" policy, which for the scale Cloudflare operates at, seems pretty impressive.

Yes, and we set up all the tooling for that and I would look at the output every single day and keep an eye on what was happening. Any team that didn't fix a crash quickly got a personal message from me. That responsibility has been taken over by others now.
