简介
Salesforce has posted a ton of information about their major outage two weeks ago. It involved a change to their DNS system that combined with an issue in BIND daemon shutdown that prevented it from starting back up.
The analysis goes into great detail on the fact that an engineer used the Emergency Break-Fix (EBF) process to rush out the DNS configuration change.
In this case, the engineer subverted the known policy and the appropriate disciplinary action has been taken to ensure this does not happen in the future.
