Single source of truth for PCL
During a recent PCL (Production Change Lock) we experienced some confusion due to there not being a single source of truth.
Sources of truth:
The Slack announcement stated the end of the PCL to be 2023-04-11 09:00 UTC.
The handbook documentation change did not have full timestamp granularity, thus it became 2023-04-10
(presumably intended as inclusive, the PCL ending after this date). This then carried over to other sources mistakenly ending the PCL on 2023-04-10
.
Recommendations
- We should identify all tooling that needs to be PCL aware.
- We should decide on a single source of truth for PCL and make all tooling respect that source.
- We should require minute-level granularity when specifying start and end time to avoid ambiguity.
