Is it possible to configure interface redundancy so that if 1 interface on the master CSS fails, it fails over all interfaces configured on the master css, effectively failing over the whole box if there is an interface failure.
This concept of failing over all virtual routers when a single fails is what is referred to as "fate sharing". Typically it is done by configuring identical critical services to all virtual routers on a CSS. This is sufficient for the vast majority of installations.
There are some rare situations where this will not be the best solution. In software version 7.3 a new feature called "VRID Peering" was introduced. You can tie multiple routers together so they are bound. This would be similiar to HSRP tracking on a Cisco router.

Another way to account for this if your traffic volume allows, would be to trunk both/all of your circuits over a single physical interface. I do this on one of my gigabit interfaces and it works well with VIP/Int redundancy.
