[BBLISA] Internet service and power outages?

[David Allan]

Just another anecdotal datapoint, one of the guys I work with telecommutes
a lot on his cable modem, and the last time his power went out for a
couple of days he was able to get online as long as his UPS held out,
which was a day and a half of intermittent use.  I don't know if he had
any services beyond internet access, but that held up at least.  I also
don't know how widespread the outage was that took out his power, although
IIRC, it was more than just his house.

Also, Comcast claims that my cablemodem has an internal battery that will
permit VoIP to stay up through a power outage, but I don't really use my
landline all that much, so I haven't bothered to test it.
