DNS regression back to old IP

[SLSTEK]

Please check to ensure that www.tullatalk.us and www.tullatalk.com point to the new www01.powweb.com server IP. They were both pointing correctly during the past couple days after transferring the site and the DNS cache cleared, but www.tullatalk.us has regressed and is now point back to the old Callisto serve again.

Our Charter DNS servers may be messed up or regressed instead, but just would like you guys to please double check. Anything change in the past day on the Powweb DNS server mappings?

Thanks...

I done a tracert to both domains from here and they both came back with the same server IP numbers (which I believe is the new platform IP's)

Here is part of each tracert:

Thanks jj -- I am thinking our Charter DNS servers are the culprit this time. Twas working good for two days and then one reverted back to the old address. When I checked on www.network-tools.com to get a current but remote tracert to both, they were showing the old Callisto server address again tonight, but had cleared a couple days ago showing the new www01 IP addy, as it should. So not real sure just what is happening here.

We will give it a little time and see if it reverts back; I have never seen one go backwards after all the caches clear (so it seemed for about two days), must have had a crash and restored an old address table on Charter's DNS or somewhere...

Problem is back again, 3 times in 6 days. Was working great again yesterday for all DNS translations for our site, but now pointing back to Callisto server.

Is anybody else have any extended DNS IP translation or cache flushing problems for their site, i.e., going back and forth from old site to new site?

Just trying to get any correlation with possible problem others may be having and trying to determine if it is a local Charter DNS problem...

I tried a traceroute from http://www.network-tools.com/ and I see what you mean, it is being directed to callisto. However, I tried a traceroute from my computer, and got there just fine:

Accessing your website from my browser works just fine also. I have no more clue than you do as to what's wrong here.

Thanks Jeff321 -- it is crazy indeed. I have used www.network-tools.com to try to help track it down and it has shown bad, good, bad, good, bad, good, and now bad over the past 6 days. Today it shows as bad (the old Callisto server). The same thing is happening with our Charter DNS servers too. The fact that it is happening with Charter's DNS servers and with independent network-tools site, makes me suspect something funny happening with Powweb's DNS stuff.

Maybe a new form of internet DNS thrashing, DNS ripple effects, DNS translation waves, who knows and crazy indeed. :)

I can force a translation in my "hosts" file manually and it works (did this for diagnostics and testing), but others seem to be having the same translation problems too, i.e., it changing back and forth from day to day.
