Before, I have registered my nameserver using ip's from Host A. I got new host and registered the nameserver using ip's from Host B. After 2 days domain are propagated and I can use my website at new host (B).
The weird is 1 day later, my website goes back to old site at Host A but I still using name server from Host B.
Hmm, that is strange. It appears that everything has been propagated correctly. Could you please email us at [email protected] so we can look at the domain(s) that are having this problem?
