I have several sites that I use my own nameservers. I moved them all to a new server yesterday and duly modified the IP with my domain registrar (123reg).

They looked as though they propagated pretty quickly. This morning I was working on one of the sites, made a change to a page, uploaded it to new server, viewed results, changed it again, uploaded, viewed results. Then next time I viewed it the site was back to pointing to the OLD server!

So I have been on to my hosts about this and they are adamant it just hasn't propagated and to wait.

How does this work? Surely, if all my sites are on my nameservers then wouldn't they all propagate at the same time? How come just one out of 65 sites hasn't ?

For what it's worth I haven't gone to the registrar as they are more than useless. When I couldn't see how to modify the nameservers ip in my admin I rang them up to ask them and they assured me they couldn't change the IP! I had to ask somebody else who also used them.

How does this work? Surely, if all my sites are on my nameservers then wouldn't they all propagate at the same time?

Nope. Each DNS zone will have different serials and TTLs, so will propogate at different times. And it could be that that zone had just expired and updated before you changed the A records, and so would then not update until the next expiry.

Thanks Chris

I didn't actually change A records or touch the dns zone. I just updated the IP of my nameservers.

What I really am very confused about is the fact that I was updating to the new server and SAW my updates. I know I'm blonde and female but.....

OK I am sure that something weird is going on, perhaps somebody here can enlighten me?

Forgetting the site first mentioned in this thread. I thought I would try out Wordpress, which I have not used before. I had a site that has been sitting empty so went to the cpanel by typing http://www.mysite.co.uk/cpanel no probs there, went in and got it to install wordpress - it went through it no problem and said it was installed, so I went to the site and it hadn't installed it. Went back to the cpanel and it say wordpress - none installed.

Checked the server with my ftp and all the files are there. So I was in cpanel, it DID install wordpress onto my new server, but then jumped back to pointing to the old server???

It is simply a matter of how your request was routed. The last time it was routed through a zone that had not updated.

It will all resolve and then be stable.

It could depend on your ISP as well, if they run several DNS servers you could be routed via an old zone version.

Give it 24 - 48 hours and it should have fully propogated.

Thanks. I just thought I was going mad! It's like that magician trick - now you see it now you don't!!

If you need to point your domain to some certain IP for development purposes only, you may add record to your hosts file. This will let you to not rely on DNS propagation.
