All Ips have been changed. If you must access your site immediately via the domain name, AND you still cannot see it, AND you run windows, try this from the command line:
(AKA the "run" option in the start menu)
Type this:
However that's only for sites you viewed recently or during the outage.ipconfig /flushdns
People that are trying to access your site after the IP change will immediately be directed to the new site. Just because you cannot see it, does not mean they don't. It only affects SOME people who were trying to access their site during the outage.
Visitors to your site during the outage may or may not have to do this depending on their ISP. Those that do "need to do this" really don't have to do anything, their ISP will update their cache data soon about your website's IP address and it should work like normal shortly.
The above method was only suggested for those site owners that require immediate access via the domain name.
