Hi all,
As many of you know, there is a risk of Blazegraph, Wikidata Query Service’s backend, catastrophically failing before we are able to properly scale the service.
Thus, it is important for us to have a playbook for what actions we will take in the event of such a disaster, as well as making that playbook transparently available.
This Blazegraph failure playbook https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/Blazegraph_failure_playbook is now available, and we welcome you to take a look at it, though we hope to never use it.
Best, Mike
