Following the 2020-07-23 WDQS Outage, it was recognized that given WDQS exposes a public endpoint with the potential for overly expensive queries to compromise service availability by knocking WDQS instances offline, we need to create SLOs and an error budget accordingly and publicize it .
Note that a similar discussion was already started on T199228. It was closed, waiting for architectural changes to be implemented first.
Will this ticket be resolved by the dashboard built for https://phabricator.wikimedia.org/T293027 and a final SLO value we settle on?
Ryan will add a quick blurb in https://wikitech.wikimedia.org/wiki/Wikidata_Query_Service about the SLO with a link to the dashboard, at which point we can move this to Needs Reporting.
Also we (Ryan/Brian) should mention the SLO in our next SRE meeting.
@RKemper it might make sense to also update https://wikitech.wikimedia.org/wiki/SLO#Published_SLOs
