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.

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 is now available, and we welcome you to take a look at it, though we hope to never use it.

Best,
Mike
