There is one router on the Comcast side, which is a single point of failure. There is one circuit to your prem, which is a single point of failure. To connect two routers on your end you must terminate the circuit in a switch, which is a single point of failure. And yet, in the face of all that somehow running two routers with two BGP sessions on your end increases your uptime? The only way that would even remotely make sense is if the routers in question were horribly broken / mismanaged so (had to be?) reboot(ed) on a regular basis. However if uptime is so important using gear with that property makes no sense! I'm pretty sure without actually doing the math that you'll be more reliable with a single quality router (elminiation of complexity), and that if you really need maximum uptime that you had better get a second circuit, on a diverse path, into a different router probably from a different carrier.
