Hi all,
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].

Hi all,
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.

Downtime is over - WCQS beta service has been restored from the latest (available on Monday) dump. Unfortunately, due to the issue with skolemization for SDC dataset, using skolemized blank nodes change was reverted - we will be working on figuring out what's the problem.
Have a good day, Zbyszko

Hi all,
We managed to get skolemization working correctly for the WCQS beta instance. As a reminder - this only affects WCQS, but there's a preview available for WDQS as well [1] and we will be switching WDQS to skolemized blank nodes in the near future.
Have a good day, Zbyszko
