Thanks as always for this report, Timo.
One reason the count is higher in May is because that's when the Growth
team began implementing a chores process
<https://www.mediawiki.org/wiki/Growth/Team/Chores> (credit to Readers Web
for the inspiration <https://www.mediawiki.org/wiki/Readers/Web/Chores>) to
systematically review and log production errors that appear on our team
dashboard
<https://logstash.wikimedia.org/app/kibana#/dashboard/AWl4jlZ78aQffZ3Ho7BV>
in Logstash. (We've also implemented a triage process for our inbox
<https://phabricator.wikimedia.org/project/board/1114/>, which used to have
~2000 tasks and is now at 10.) Some of the tasks we've filed from Logstash
are probably duplicates or close relatives of existing production error
tasks, but because we are trying to timebox our triage process, we don't
always succeed in ensuring that we identify existing tasks before filing
new ones.
A bigger problem is how to handle our growing pile of tasks that need some
attention; as a team that's tasked with feature development, making time to
work on maintenance tasks unrelated to the code we touch day-to-day is a
challenge. So, while we are going to be more diligent about filing tasks
when we see issues in Logstash, unless something appears to be badly
broken, it is probably going to stay as an open task.

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.
