over 48 hours ago we have added 4 new NS records for a subdomain and we still cannot see all of them on DNS Checker - DNS Propagation Check & DNS Lookup. Just about 5-6 at a time. And they keep changing.
We have used the same NS records for another subdomain a couple of months ago and everything has been working fine.
I tried to:
- remove them and add again
- change the TTL from auto to 1h and back to auto after about 6 hours
- they are not proxied (DNS only, grey cloud)
Any ideas about what might be causing this delay?
Thanks for help,
