one piece of feedback from Aaron's recent retrospective (not sure if we have a public link for it?) that I felt was a very good advice was that we should track the number and type of incidents (an incident being when something maintained by the multimedia team breaks in production) so that we can get an overview of how good our QA/CI practices are and what needs to be improved.

With that in mind I created this page: https://www.mediawiki.org/wiki/Multimedia/Incidents

Please expand it whenever something comes up (or even with older events if you still remember them).
