The recent outage resulting from severe weather prompted us to develope a system whereby the DNS servers actively monitor the health of the webservers and update the DNS records during an outage to ensure that the webpage is always available.  This is subject to the caveat that DNS is a distributed system with caching so there will be propagation delays.  The Time To Live has been set low (5 minutes) on the webserver records to reduce this as much as possible.
