Hi all,
We experienced WDQS service disruptions on 2020/07/23. As a
result
there was a full outage (inability to respond to
all
queries) for a
period of several minutes, and a more extended
period of
intermittently degraded service (inability to respond to a
subset of
queries) for 1-2 hours.
The full incident report is available here:
https://wikitech.wikimedia.org/wiki/Incident_documentation/20200723-wdqs-ou…
Ultimately, we traced the proximate cause to a series of
non-performant queries, which caused a deadlock in
blazegraph, the
backend for WDQS. We have placed a temporary
block on the
IP address
in question and are taking steps to better define
service
availability
expectations as well as processes to make
detection of
these events
more streamlined going forward.
What was the problem query?
I ask because I would like to try it against our Wikidata
endpoint at:
https://wikidata.demo.openlinksw.com/sparql .
We have an "Anytime Query" feature designed for these kinds
of problems,
hence the vested interest in these kinds of problem queries.

Hi, do you like citation networks? Already 51% of all citations
are available <https://i4oc.org/> available for innovative new
uses <https://twitter.com/hashtag/acs2ioc>. Join me in asking the
American Chemical Society to join the Initiative for Open
Citations too
<https://www.change.org/p/asking-the-american-chemical-society-to-join-the-initiative-for-open-citations>. SpringerNature,
the RSC and many others already did <https://i4oc.org/#publishers>.
