Hello all,
Since we recently received several messages about tools unable to access
the Query Service, I wanted to remind you about this email from Guillaume,
and especially this part:
"As a reminder, any bot should use a user agent that allows to identify
it:
https://meta.wikimedia.org/wiki/User-Agent_policy."
If you're a tool builder and encountering issues with WDQS at the moment,
please check that your tool is compliant with those guidelines.
Thanks for your understanding,
Léa

Subject: [Wikidata] Overload of
query.wikidata.org
To: Discussion list for the Wikidata project. <wikidata(a)lists.wikimedia.org>
Hello all!
We are currently dealing with a bot overloading the Wikidata Query
Service. This bot does not look actively malicious, but does create
enough load to disrupt the service. As a stop gap measure, we had to
deny access to all bots using python-request user agent.
As a reminder, any bot should use a user agent that allows to identify
it [1]. If you have trouble accessing WDQS, please check that you are
following those guidelines.
More information and a proper incident report will be communicated as
soon as we are on top of things again.
Thanks for your understanding!
Guillaume
