It’s usually held up as an example of how clever the engineer running the network is about resilience. “You see,” the diagram asserts, “I’m smart enough to purchase connectivity from two providers, rather than one.”
Can I point something out? Admittedly it might not be all that obvious from the diagram, but… Reality is just about as likely to squish your network connectivity like a bug no a windshield as it is any other network. Particularly if both of these connections are in the same regional area. The tricky part is knowing, of course, what a “regional area” might happen to mean for any particular provider.
The problem with this design is very basic, and tied to the concept of shared link risk groups. But let me start someplace a little simpler than that—with the basic, and important, point that putting fiber in the ground, and maintaining fiber that’s in the ground, is expensive. Unless you live in Greenland, fiber can be physically buried pretty easily (fiber in Greenland is generally buried with dynamite by a blasting crew, or Continue reading
