Why, do you think, the Internet may stop working when the power
goes out?

It should not, which is required to certain ISPs by regulation at
least in Japan.

"voice chat"? Are you assuming PCs?

POTS telephone devices and terminal adaptors is the natural way
of "voice over the Internet".

Note that end to end architecture means ultimate availability of
fate sharing.

PS

According to the end to end principle, end user equipments should
have their own power backup, of course, which is also the case with
ISDN TA or cellular phone devices. Then, with multihoming, your
connection is a lot more robust than that of a single telephone
company.
