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

Hi Mike,
maybe change the word "delete" to "move" to make it sound less contentious.
These so called subgraphes can easily be hosted elsewhere within the realm of the Wikimedia Foundation domain or externally. And still be linked to and be queryable by WDQS on alternative backends.

Ok, just looking at the FAQ Mike. looks like federation is not part of your playbook at this point in time.
Though I personally would like to see more federation at wikidata.

We all want to, I think. Nothing says that federation will not solve the problem in the future, but this playbook is for the situation *as it is*. I am among the hopefuls that, in the future, federation and other things might prevent the catastrophic scenario, but unfortunately preparations for the worst should always be founded on what the situation is, not what the situation should be or can be.
