    ISP slow at updating DNS records?


    I have a site hosted with a domain, and we are switching servers. I change my nameservers and wait for them to update. When I look at the status of my site a few hours later it says that it is up. But when I go to it in my browser it is still pointing to the old nameservers. When I go through a proxy server hosted outside my network, I see the updated nameservers. But again, when I try browsing it without a proxy I get the old site. I have cleared all cookies, saved sessions, offline stuff, and even restarted my modem / computer. I don't understand why I can't see an updated website, but everyone else can. Should I consult my ISP about this issue? Is it their fault?

    First you need to know how DNS works ( try here )

    Your ISP has probably cached your DNS info (as you have looked at it within it's refresh time).

    Normally DNS is set ti require a refresh every 12-24 hours (21600 seconds / 6 hours is the norm if i remember correctly), So your ISP will not bother checking this record again for another x amount of seconds.

    If your ISP is not cacheing your DNS. Maybe your PC is (try ipconfig /flushdns).

    Nevertheless within 24 hours, you should see the changed have taken place

    Hope this helped

    Did the dns flush and didn't really do anything. I guess my only option is to wait.

    what i normally do, a day or so before i am due to move, is change the TTL on my DNS records to something stupif like 60 seconds.

    Normally circumvents that issue for me

    You bet!!

    As above - change the record expiration value, if your DNS server can handle increased traffic as a result.
