Trends
In April, we saw a continuation of the healthy trend that started this
January
<https://phabricator.wikimedia.org/phame/post/view/227/production_excellence_28_january_2021/#trends>
— a trend where the back of the line is moving forward at least as quickly
as the front of the line. We did take a little breather in March
<https://phabricator.wikimedia.org/phame/post/view/229/production_excellence_30_march_2021/#trends>
where we almost broke even, but otherwise the trend is going well.
Last month we bade farewell to the production errors we found in July 2019.
This month we cleared out the column for October 2019.
One point of concern is that we did encounter a high number of new
production errors — are errors that we failed to catch during development,
code review, continuous integration, beta testing, or pre-deployment
checks. Where we used to discover about a dozen of those a month, whereas
we found 42 during this month. As of writing, 17 of the 42 April-discovered
errors have been resolved.
The "Old" column (generally tracking pre-2019 tasks) grew for the first
time in six months. This increase can largely be attributed to improved
telemetry of client-side errors uncovering issues in under-resourced
products, such as the old Kaltura video player.
