Incidents
Zero incidents recorded in the past month. Yay! That's only five months
after November 2020, the last month without documented incidents (Incident
stats <https://codepen.io/Krinkle/full/wbYMZK>).
Remember to review Preventive measures
<https://phabricator.wikimedia.org/project/view/4758/> in Phabricator,
which are action items filed after an incident.

Trends
In May, we unfortunately saw a repeat of the worrying pattern we saw in
April
<https://phabricator.wikimedia.org/phame/post/view/235/production_excellence_31_april_2021/#trends>,
but with higher numbers. We found 54 new errors. This is the most new
errors in a single month, since the Excellence monthly began three years
ago in 2018. About half of these (29 of 54) remain unresolved as of
writing, two weeks into the following month.

New errors in May
Below is a snapshot of just the 54 new issues
<https://phabricator.wikimedia.org/maniphest/query/tmkGqt0C93YG/#R> found
last month, listed by their code steward
<https://www.mediawiki.org/wiki/Developers/Maintainers>.
Be mindful that the reporting of errors is not itself a negative point
per-se. I think it should be celebrated when teams have good telemetry,
detect their issues early, and address them within their development cycle.
It might be more worrisome when teams lack telemetry or time to find such
issues, or can't keep up with the pace at which issues are found.
