Yesterday I changed my DNS servers to point to a different server. This change has still not been displayed on my own computer, but it does from other computers around the world (checked using browsershots.org) I'm using OpenDNS for my DNS and there cache is pointing to the correct server. What could be meaning my computer still isn't going to the right place? Thank you! |

It takes a while for changes to ripple around the world, so I'd give it a bit longer. Another possibility is that you have a hosts file (in /etc/hosts or c:\windows\system32\drivers\etc\hosts depending on your operating system) that has the IP address hardcoded in it. |

Everyone should see the updated record change somewhere between instantly and the relevant TTL value set on the record. But in practice they don't and you experience what you are seeing. A lot of ISP's don't honour the Time to Live TTL value and hold on to the old record for longer, some badly configured caches may not see the change if the TTL value is very low as they ignore TTL's below a certain value. I have also seen a DNS change come into effect on a machine then a couple of hours later it reverts back again and flip flops for a while like this. Very confusing. It might be worthwhile flushing your machines DNS. This can sometimes help speed up the change ipconfig /flushdns if you are on windows. |
