Ya I think someone or something borked up the migration. The glue records are missing in the .net root servers and someone added a comment to the github thread. They need to add the glue records ASAP. They should have first created the records in the new name servers and then changed the glue records rather than remove them.

Edit: (17:57 UTC) Still no glue records. They should get on the phone with their registrar.

They closed the git issue talking about DNSSEC keys but there are still no glue records. /shrug back to a video game for me.
