I am trying to change the hosting for our website. I have edited the www A record from the IP address of the old host to that of the new host. However, when I check with whatsmydns.net it still shows the IP address of the old host and the site has not updated to the new one. This has been over 24 hours now. Zoneedit checks show the new host IP address. Any ideas why this has not propagated so that I can access the new site on my new host? Thanks for any advice!
