Despite not appearing in our account, our domain cam.ac.uk still appears to be active in CloudFlare: if I do “dig ns cam.ac.uk. @earl.ns.cloudflare.com”, they return themselves as the nameservers; if I do “dig www.cam.ac.uk. @earl.ns.cloudflare.com”, I get 18.104.22.168 and 22.214.171.124, which are not our servers.
The nameservers configured for our domain are not Cloudflare and I don’t believe we ever used Cloudflare for our DNS although we did use it for www.cam.ac.uk a few years ago for an abandoned trial.
This appears to be breaking attempts by subdomains of cam.ac.uk to move their sites into Cloudflare where the origin server is under cam.ac.uk as it can’t be looked up, since Cloudflare think they’re authoritative for the domain.
The domain is not showing up under our account so there’s nothing I can do to adjust or disable anything; I assume it’s not associated with our account any more. How can I disable it?
I’m the Hostmaster for cam.ac.uk so I can stick records in there to prove I am in control of the zone, if necessary.
As I’m not a current customer I can’t directly log a ticket with Cloudflare, but I suspect I might need to contact them to find out why the domain is still there. If there anything else I can do?
