"Registration failed" in "Manage domains" in "Registrar"

Hello sir, I am getting “Registration failed” for a domain I attempted to buy using the registrar.

When navigating to manage the domain there is a box saying “You have unverified Contacts. View Contacts”. Accessing the “View Contacts” link gives a “It looks like we’re having some internal issues.” page.

Identical errors for me, too.
“Registration failed” for newly-registered domain, and an internal error when attempting to sort out unverified contacts.

The domain itself does seem to be correctly registered when using whois, and DNS queries all seem to respond correctly.
