A List of Post-mortems

Public incident reports grouped by failure themes such as configuration, time, hardware, and databases. Useful for testing assumptions before an outage.

How to use it

  1. 01

    Read reports from the original operators rather than only their summaries.

  2. 02

    Look for interacting conditions and failed recovery assumptions across incidents.

Keep in mind

Public postmortems are selective accounts. They do not reveal every internal detail or establish failure rates across organizations.

Put it to work

Try this next

Choose two incidents in the same failure family and ask which shared conditions exist in your service.
