We run a small web server in our office, using a pretty fast business grade cable connection (Time Warner).
Occasionally, this connection drops out. We have a backup DSL internet connection, and a router capable of fail-over. So when our Time Warner goes out, the DSL automatically switches on, and this seems to work well.
Our issue is, our website is accessed via subdomain.domain.com, and when the TW connection drops, the subdomain.domain.com is still pointed to TW, not the DSL.
Is there anyway to have the domain roll-over as well?
