I've just moved a site from one server to another. Both servers are under the same Media Temple account - so the nameservers haven't changed, just the IP address.
To help verify the move has taken place, I added a hello.html
to both servers, which says 'Hello from the (NEW / OLD) server', respectively.
On my laptop, Chrome indicates it's seeing the new server. Firefox, Opera and Safari still say 'hello from the OLD server', despite hard refreshes, cache clears, etc.
Using the IP lookup tool at http://www.hcidata.info/host2ip.cgi, ALL browsers indicate the domain name is pointing to the NEW IP address, despite some of those same browsers showing the OLD hello.html page.
I know DNS changes can take time to propagate, and during that time you can get varying results from different locations. But this is all testing from the same computer.
Any idea as to what's going on? And how to ensure all browsers point to the version of the site on the new server?

UDPATE:
So I connected from a different place (work, not home) and everything started seeing the latest version. Then, when I returned home, the latest versions stuck. So, it's all working. I'd still be interested to find out what specifically the issue was before - but I'm guessing it's unlikely I'll ever know for sure!
