You might have heard the story of how someone accidentally deleted his entire hosting customers’ websites (1500+ customers).
Last night I accidentally ran, on all servers, a Bash script with a rm -rf {foo}/{bar} with those variables undefined due to a bug in the code above this line.
All servers got deleted and the offsite backups too because the remote storage was mounted just before by the same script (that is a backup maintenance script).
We’ve all made mistakes in our life that we’ve needed to take responsibility for… but oh man.
