Hi all,

I'm sorry for crossposting from commons-l, but from our experience, WCQS is
in the area of interest to Wikidata users.

Due to  low disk space on the WCQS beta instance and possible data
corruption that might've happened because of it, we need to take down WCQS
beta and rebuild its journal - operation should take about 2 days -
starting now. I'm sorry for any inconvenience this may cause.
This is a recurring issue, but we have a permanent solution in the pipeline
on which we plan to start working on soon: [1].

We are using this downtime to introduce blank node skolemization to WCQS
Beta[1]. This change is a prerequisite on our future work on real time
updates for that service.
