First Postmortem

So what is an autopsy? An autopsy is a written record of an incident. Among other things, it documents the impact of the incident, what caused it, the actions taken to mitigate or solve it, and how to prevent it from happening again.

We need to accept failure for autopsies to work. This includes having irreproachable autopsies and not pointing the finger when looking for fundamental causes. Human error is never a root cause.

When to write an autopsy? A good rule of thumb is to write one if an incident has an immediate impact on users (downtime or loss of data) or if an interested party requests it.

Summary of issues:

At 1:35 a.m. On February 17, 2020, the official Andrea Carrillo (@foggyex) launched an ad campaign on Facebook. The objective of the campaign was to apply distrubuir advertising by facebook by paying per click on this network. In three hours, Facebook responded with many people asking about the product. The ad was left with the wrong company name so many people when searching for the company did not find it and decided not to make the purchase, affecting a high percentage of users.

Lessons Learned – to prevent the same error in the future, a person different from the person in charge of publishing these notices will be appointed to avoid errors and have another point of view
