I wonder if anyone ever looked into this and found anything: I noticed that a few days ago Google began renaming sites. In our case `T-Online` became renamed to `` but it’s not only us but a lot of other publishers as well. From what I can see there is no obvious reason. We trying hard to be very consistent (schema, feeds, …) but it looks to me like Google just doesn’t care at all.
While I don’t have a problem with the renaming itself I wonder if Google does use schema-markup at all or if it is retired at this point similar to rel=prev/next
