Hi!
Thank you for wearing the {{User loves OpenRefine}} userbox on your user page!
Because the existing Wikidata reconciliation service has had severe performance issues recently, I have created a new one which should be faster and more robust. You can add it to OpenRefine in the reconciliation dialog with the following URL: https://wikidata.reconci.link/en/api (or by replacing en by any other language code).
If you have any issues with this new service, let me know.
