Hi all,
We need to re-image our host wdqs1009.eqiad.wmnet, which is the test host powering *query-service.wikidata.org http://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.
