Response from Speedera.com...
World Wide Wireless does in fact subscribe to our Web Site Fail over service.
Basically we probe their origin server (63.194.202.68) to see whether it is up or not. If not, their site will fail over to one of our backup server. However in order for this to work, customer DNS must not be down because it has to communicate with our DNS to determine what IP should be resolve for the website.
Normally when customer origin site is up, our DNS will answer back to World Wide Wireless DNS request with their origin server IP. Their DNS server would then return the IP back to the client requesting their site. If we detect that their site is down, our DNS would send back to their DNS the IP of one of our backup server. Their DNS would then return the IP of our backup server to the requesting client.
When a client makes a request to go to the website, it must go to World Wide Wireless DNS first before going to our DNS. World Wide Wireless controlled their DNS.
If their DNS server is down, then our fail service would not work since their DNS need to be able to communicate with our DNS to resolve the IP. Our website fail over service only fail over customer origin site and not their DNS. Customer DNS must be up and running properly in order for our service to work. In this case World Wide Wireless DNS is down. We have left several voicemail and email to World Wide Wireless to let them know that their DNS is not working. As of now, we are still waiting for their response.
