document status: draft
What happened? Write one paragraph or at most two, including UTC timestamps for key events like the start and end of the outage. Briefly assess the impact: for user-facing outages, estimate how many queries were lost, how many users were affected, or which populations (editors? readers? particular geographies?), etc.
Avoid assuming deep knowledge of the systems here -- but if the incident is too complex to sum up in a couple of paragraphs, this lightweight format may be a bad fit.
TODO: Add the #Sustainability (Incident Followup) Phabricator tag to these tasks.
