A few moments ago, the Battle.net catalog was updated and the Patch 10.0.5 PTR has been renamed to the Patch 10.1 PTR.
The servers are still on Patch 10.0.5, but the name has been updated on the Battle.net catalog to Patch 10.1! As the servers are still on Patch 10.0.5 and the change was just in the name, there is no datamining available at this time.
