Hello
A server switch will happen on September 25, at 15:00 UTC. All wikis will
be in read-only mode for a few minutes.
We will inform communities as we usually do, through Tech News. Also, a
banner will be displayed 30 minutes before the event. We need your
assistance to inform your communities through local channels.
You can link to the information page we usually use: <
https://meta.wikimedia.org/wiki/Tech/Server_switch>.
Thank you in advance,
Benoît

Hello lovely ambassadors,
I am forwarding an email about an upcoming change for the Wikidata Query
Service. This is relevant for you or your community if you rely on SPARQL
queries to Wikidata that touch Items for scholarly articles.
If you have any questions please don't hesitate to ask on the talk page.
Cheers
Lydia

Subject: [Wikidata-tech] [BREAKING CHANGE ANNOUNCEMENT] Wikidata Query
Service graph split available in production; scholarly entity queries
require migration by March 2025

Hi all!
As part of the WDQS Graph Split project,[1] we have new SPARQL endpoints
available for serving the “main”[2] and “scholarly”[3] subgraphs of
Wikidata.
As you might be aware we are addressing the Wikidata Query Service
stability and scaling issues. We have been working on several projects to
address these issues. This announcement is about one of them, the WDQS
Graph Split.[1] This change will have an impact on certain uses of the
Wikidata Query Service.
We are now entering a transition period until the end of February 2025. The
three SPARQL endpoints will remain in place until the end of the
transition. At the end of the transition, query.wikidata.org will serve the
main Wikidata subgraph (without scholarly articles). The query-main and
query-scholarly endpoints will continue to be available after the
transition.
If you know to want more this change, please refer to the talk page on
Wikidata.[4]
Have fun!
Guillaume
