Over at www.broadbandreports.com a VOIP forum member has noted an interesting problem. When he suffered a power outage he also lost his cable modem service. This despite the fact that he dutifully provided a UPS solution to keep his network gear running. We can infer that the CableCo doesn’t provide similar UPS capability in the local cabinets serving his area.
This is in stark contrast to Telco’s, who historically provide continuous service through power outages. They have put huge effort into achieving 99.999% uptime, and continuous power is a major consideration.
