Recent tally
72open, as of Excellence #22 (Jul 23rd).
-16closed, of the previous 72 recent tasks.
+13opened and survived July 2020.
+37opened and survived August 2020.
106open, as of today (Sep 23rd).

Previously, we had 72 open production errors over the recent months up to June. Since then, 16 of those were closed. But, the 13 and 37 errors surviving July and August raise our recent tally to 106.

The workboard overall (including tasks from 2019 and earlier) held 192 open production errors on July 23rd. As of writing, the workboard holds 296 open tasks in total. [4] This +104 increase is largely due to the merged backlog of JavaScript client errors, which were previously untracked. Note that we backdated the majority of these JS errors under “Old”, and thus are not amongst the elevated numbers of July and August.

🎉   Thanks!

Thank you to everyone else who helped by reporting, investigating, or resolving problems in Wikimedia production. Thanks!

Until next time,

Narrator: “What!?” Tyler: “The things you own..., they end up owning you.”
