Google Webmaster Tools apparently have a limit of adding 1000 "domains"/URLs and we did reach that limit and can't add any new ones. (as mentioned in T98283 and other places).
This is a ticket to discuss that issue separately from access requests to existing domains.
Options seem to be:
- delete existing ones that are not needed or used
- add an additional account , like a "noc2@"
- contact Google and ask if the limit is set in stone or we can have an exception because Wikipedia
