Due to some continued overuse of the Wikidata Query Service, and the SPARQL endpoint, we recently implemented a throttling feature to prevent users and bots from using too many resources on the servers. 

Here are the new limits:

* any user that is identified by IP and User Agent, can use the service for 60 seconds of query time per minute (burst at 120 seconds per minute)

* any user query can generate up to 30 errors per minute (burst to 60 errors per minute)

Please let us know if there are questions or concerns with the new usage limits, as we are able to fine tune them if it is causing problems with reasonable use cases.

Thanks for your understanding!
