DNS Questions

[Dan]

What do you do when you change your nameservers and (only for yourself) keeps switching back between the right and wrong ones? I guess it happens because you change them, and in the middle of them changing, go to your domain and it goes to the old ones.

I tried restarting my computer, doing ipconfig /flushdns which I know does nothing, and even switching what DNS servers my computer uses (OpenDNS and my ISP.) I still got an error saying that Firefox couldn't find the server, but everyone else I asked got the right page. :td:

i found this also when i have refcontrol addon for firefox so i never used it. what do you think plugins/mod are in your firefox that influence this? can we do isolation, can you uninstall one by one your addon/plugins on firefox and see which addon when removed can access the said url?

I know it's not a plugin blocking me from the site, because I couldn't get my mail from Outlook, either.

I assume it has to do with my own computers cache of the DNS, but I don't know what else I could do to make it update.

i can't suggest anything seems opendns is all ok http://system.opendns.com/
have you tried using http://www.dyndns.com/ ?

using web proxies will also help usually i will only use one web proxy and i can see the difference even browser cache is most of the time sticky in the Philippines.

DNS changes can take up to 72 hours to propogate. This is due to cached entries on DNS servers that have recently looked up the domain. You seem to be aware of this as you tried two different DNS servers. IPConfig /flushdns works for cached entries on your computer. If you administered your own DNS server, you could flush the cache on it as well to clear up the problem. However, I doubt your ISP would do that for you. Maybe you just got unlucky and both your ISP and OpenDNS had cached entries for the old servers.
