Hi J.P. and others,
I have a dog in this fight (I work for ImageStream), but this comment applies to just about any situation/hardware. Set up redundant routers using BGP and VRRP (HSRP in Cisco.although apparently they support VRRP also). If you can't afford to be down, you need to find a way to get another router. If your upstreams are Ethernet, this is pretty simple, and not terribly expensive (depending on the hardware you choose). You can peer with different types/speeds of circuits. You'll need to do some preliminary work to manage the flows so that you don't kill the smaller feeds, but it's very doable.

Works great for that; no reliability issues in every day operation. No problems with 12 month uptimes. I have seen some minor issues in 3.30 where if you remove a peer prior to disabling first, it can jam things up in terms of stale routes, but done in the right order it's fine. Once a month crash is not acceptable reliability for our uplink. Once in 6 months is OK if it's self-correcting. I've used Cisco for about ten years for my uplink with BGP, and it has been good as long as we didn't run out of memory or have a rare hardware problem. We kept a complete working spare system in place for parts and didn't have a Smartnet contract. I had a smartnet once for a smaller router, but it was so much trouble getting it and using it for just one router, I never renewed it. We have a Juniper j2350 with aftermarket ram now replacing a Cisco 7507. It's been as/more reliable than the Cisco and is 2u instead of dorm-fridge size, gigabit ports instead of 100mbps ports. Tech support was excellent. I'll be buying a spare or bigger one for backup. I have not tried Imagestream, but don't doubt the wide variety of other's praise. As networks get bigger and thus more complex, it's essential to avoid unreliable situations, no matter what the cost savings. Say you have 60 devices and each one has a once-a-month breakage. That's 2 outages a day, enough to drive staff and customers crazy. Reduce that to twice a year outage per device and that staffer can get something done again.
