I'm not sure what's going on, it's an assumption based on what's happening on our site. Maybe the data has been rolled back for only a few domains?
If you had a sudden spike in crawl errors, maybe you're part of that group.
As of today, the index still shows old URLs that don't exist for our site.
It could all be a site level issue too. It's hard to tell.
