Not sure if this is the right forum, but you're such a smart group [:)] that I thought I would ask:
I have an ASG 220 with a T1 primary interface and a DSL interface configured for failover.
Our website and DNS are hosted elsewhere but I have an internal webserver and email Exchange Server.
I believe that DNS for the mail server is not a big issue because I can configure the 2 MX records with a priority 10 and a priority 100 so the second ip address will only be used if the first is not available.
But what about the owa web server? If I put out 2 different ip addresses for the owa.oursite.com server and only 1 of them is available, won't I get DNS failure at least some of the time?
Does the hosting company have to provide some kind of failover DNS service or is there a simple way to resolve this?
