[Wikitech-l] Production Excellence #34: July 2021

[Krinkle]

How’d we do in our strive for operational excellence last month? Read on to
find out!
Incidents

3 documented incidents last month. That's at the median for the past twelve
months, and slightly below the median of 4 over the past five years (Incident
stats graphs ).

   - 2021-07-14 eventgate latency spike
   

  - Impact: For ~ 10min MediaWiki API clients experienced request
  failures.
   - 2021-07-16 codfw-a2 network
   

  - Impact: For ~ 1 hour Restbase clients received errors, affecting
  mobile apps and ContentTranslation.
   - 2021-07-26 ruwikinews DynamicPageList
   

  - Impact: For 30min, 15% of requests from contributors on all wikis
  failed. There were also brief moments during which no readers could load
  recently modified or uncached pages.

Learn about past incidents at Incident status
 on Wikitech. Remember
to review and schedule Incident Follow-up
 in Phabricator,
which are preventive measures and other action items filed after an
incident.
Trends

Last month the workboard held 154 non-old unresolved error reports. Over
the past thirty days, the collective efforts of our volunteers and
engineering teams have closed 14 of those.

In the month of July we've also introduced or discovered thirty-one new
error reports (that's an average of one production regression every day!).
Of those new error reports, fifteen were resolved and 16 remain unresolved.
The workboard now tallies up to 156 tasks.

Over on the backlog, we're continuing to ploddingly present progress on
production problems from phantoms of christmases past.

Hi Siddhi

Here's the link to the Wikimedia organization on Github:
https://github.com/wikimedia

Here's a link to MediaWiki on GitHub in case that's helpful:
https://github.com/wikimedia/mediawiki

These repositories are (mostly) mirrored from our Gerrit instance where we
do code reviews and development: https://gerrit.wikimedia.org/g/

I hope that's helpful!
