Exactly. Not having proper tooling meant they didn’t know what to do. When your check engine light comes on, you don’t replace every system in your car, you get out a scanner and check the code.

Google cloud has trace built in which could have shown them execution times and is dead simple to drop into most frameworks.

The real story here is that hey didn’t have engineering leadership on the team who knew how to properly diagnose issues, put tooling in place before launch, and understand how their system is architected.

Kudos to the engineers for solving this issue under pressure.
