We are currently experiencing DNS resolving problems of the uber.space zone. There's no problem with our DNS servers: They happily serve the uber.space zone. The problem seems to lie within the .space registry that no longer seems to serve a delegation to our nameservers. The registration of the uber.space domain is fine though, the domain is still listed with our domain registrar and Whois records show zero updates and a correct delegation. However the [abef].nic.space nameservers responsible for delegating the zone to our nameservers don't provide records any more.
We have receive similar reports from other .space domain owners, using registrations through other registrars, so we have good reason to believe that this is indeed a bigger problem of the .space registry in general, not specifically with our uber.space domain. We will keep you updated.
