Hi all,

We need to re-image our host wdqs1009.eqiad.wmnet, which is the test host powering query-service.wikidata.org. Service will be offline while we transfer its journal file (the wikidata equivalent of the database) to another server, re-image the original server, and then transfer it back. The whole procedure will begin around 18:00 UTC June 8 and will take a few hours.

This is only for query-preview.wikidata.org and not for query.wikidata.org. There will be no interruption to normal WDQS operation.

We'll send another message to the Wikidata mailing list when the operation begins.
