Hi all,

I have OpenSRS and Enom domains with weblaunching.net. I have changed all of them to point to a new nameserver two weeks ago.

Address lookup, traceroute, service scan... points to the new IP. whois lookup points to new nameservers. However, DNS records still point to old website/nameserver ns1.server2vh.com most of the time. I said most of the time because (using the same PC) http shows the new website at times and the old website at times.

The domain is projgate.com. If anyone can shed some light on this, I would appreciate it. Thanks - Howard

I had this exact thing happen to me recently.

I changed a couple of my custom nameservers and they "seemed" to switch back and forth initially.

The only explanation that I could come up with is that the old nameservers were cached somewhere along the way.

It has since resolved itself.

Sounds like it's your ISP. When an ISP refreshes its DNS cache, it usually fluctuates
from the old to the new and vice versa.

lookup the domain's NS records here: http://www.squish.net/dnscheck/

that'll tell you what root servers are reporting what.

Thanks, everybody, for replying.

My host and I ran some dns report(dnsreport.com...) and found several problems including: "FAIL: You have one or more missing (stealth) nameservers". They fixed all the errors; so, i hope I that's that.
