nodes do not cost $200,000! they cost around $10,000 from what I have been told over in one of the tech forums on the internet.

Also realize that nodes only service a few hundred homes at most and SoCal has thousands of nodes to provide service to the millions of customers.
A $200,000 dollar item may be a CMTS, which your node and lots of other connect to. It's there where the splits really need to happen since it's the CMTS port bandwidth that gets overloaded. A node is split so it can connect to more CMTS ports. A node split alone doesn't do much, if the new node is connected to the same ports as the original. A new CMTS installation can take weeks and/or months, between budgeting, design, installation, and moving nodes onto it. A CMTS also isn't installed for a single node overload, it's done to relieve bandwidth congestion on many nodes at once or to get ready for higher speeds or services.
Two is one, one is none. If it's important, back it up... Somethimes 99.999% availability isn't even good enough.
