## 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.
