GitLab database incident

For your information:

• Gitlab Database incident

• Discussion on HackerNews

Lessons learned:

• Engineers should get more sleeps

• Restore strategy is more important than backup strategy

• Testing backup plans would not be a bad idea. If we don't test backups, we don't have them. We must rechecking backup/restore plans monthly, quarterly or yearly

• Always careful, anything with sudo command, we need to double/triple check

• Change terminal PS1 format/colors to make it clear whether you’re using production or staging

  • RED for production

  • Blue/green for staging

• Show the full hostname in the bash prompt for all users by default (e.g: db1.staging.gitlab.com instead of just db1)
