Hi all,
There has been interest in having more transparency around some of the
operational problems around Wikidata Query Service, to better surface the
work it takes in keeping the service running.
Yesterday, on Sunday, 06 March, there was an outage that lasted a few
hours. During this time, WDQS was overloaded and started sporadically
blocking client traffic. This was directly related to the ongoing issues
with Blazegraph, and why our main priority has been focused on finding a
suitable replacement for it moving forward.

Apologies to all who were affected by this incident.
Best,
Mike
