You guys know we have these things in the IT department called Hot Swappable routers and switches, so that way if one router failed, the 2nd router would automatically kick in. We called it a "Router Cluster" for those technical types. It prevents failures like this.
For those who say that there isnt maintance that cant be done, well there is. You can upgrade firmware, swap clusters if you have more than one, and you can reboot during periods of maintance, we would swap clusters, blow off the dust and reboot, and swap back. We would do these things that were like fire drills, but we would act like the equipment failed even though it didnt. You know "disaster recovery" So that way, it wouldnt take hours to get back up, but min. With how big charlie is, I kind of expected redundancy like this, but when you go cheap you get failures.
