A real oddity with the DNS which I’ve encountered, and is really flummoxing me. Have put in a support ticket mid afternoon, but no reply as of yet, so thought I’d put it out there…
I recently added a file for the domain sq.gg, which has a whole raft of entries, and uploaded. All appeared to be fine, however, subsequently discovered that a whole series of CNAME entries weren’t working, including, but not limited to:
(effectively, any sub-sub-domain CNAME entries)
I later realised that I missed the top three lines of the dns file as follows:
.sq.gg::a.ns.bytemark.co.uk .sq.gg::b.ns.bytemark.co.uk .sq.gg::c.ns.bytemark.co.uk
…and added these in and re-uploading, and expected all to be hunky-dory (after a short propagation period). Unfortunately, it didn’t fix the problem.
Now, I have tried using the same style CNAME entry for an unrelated domain:
and this worked perfectly, and pretty much instantly.
So, my question is - if the DNS entry / format is fine for one domain, they why would it fail for another? Is it likely to be the missing initial records, and a case of waiting for a cache/TTL, or has doing that completely screwed things up?
I’ve tried deleting the DNS file and re-uploading, and restoring immediately, but this too had no effect?
It’s been a number of hours now, and I really need to get these records back up and running asap.
Any thoughts / ideas would be appreciated greatly.
