It turns out that it’s a cache issue. Both sites also use W3Cache with Couldflare for page cache, DNS and DDOS mitigation.
I cleared both cache systems and new registrations are working again.
It would be nice if WP Core would notify before pushing out these auto-security updates.
I always clear the cache after doing updates and, could have prevented these sites from falling on their faces if I knew when to expect the auto update, so I could schedule the caches to be cleared.
Thanks @jnashhawkins I’ve already posted there.
