Hi Dan - PMFJI ...
Maybe I'm not understanding completely. Do you have any needs that require you to have that level of HA? Must you absolutely positively have 24/7/365 access with no interruption? (If so, I think you need to leave Florida! <g>) Maybe I'm just extremely fortunate, but with our Charter Communications up here in Saginaw, MI, I have not noticed any outages AT ALL for the past three years or so. We had a few hiccups at the start and a cable modem was swapped out within the first six months, but since then we have experienced no outages (except for when power was out, of course). Not to say that there haven't been *any* outages; obviously we're not on 24/7/365 (well, with five users, including two teenagers, in the house, it seems we come close, but...), but if there are any outages, they must be few in number and short in duration.
I have both cablemodem and DSL. I started out with just the cablemodem.I have my personal web and email server in my home. I want it reachable all of the time. I have the cable and DSL set up on round-robin DNS, which gives a crude form of failover and load balancing. (Both have static IP addresses.)
The cablemodem connection is shut down for a half-hour or so overnight on a regular basis for routine maintenance. This may be happening to you too, but unless you're a night owl you're not likely to notice it.
The cablemodem connection has unplanned outages a LOT more than the DSL, although right now not only is the DSL not working but my phone service is not working period. But the cablemodem is working so my server is still accessible and I can still do my normal internet stuff.
