The FCC should have looked closer at Comcast in California. While it was
expected many people would loose home
Internet, voice, video service when their Customer Premise Equipment lost
power. The FCC no longer requires
battery backup for CPE. That is now a customer responsibility.
It turns out, Comcast's outside plant was woefully unprepared to handle
long, i.e. 24 hour, power outages. And
even when power is restored to people's homes, Comcast service is often
still down.
So I knew that telcos are required to battery backup pots, but are isp's too? I
have a dinky little provider who also provides
pots, but i have never been clear whether dsl stays up too in a blackout.

First of all DSL is not pots.
Traditional voice services run on a subscriber loop which is a pair
of copper lines running from the central office to the customer end point.
This analog voice service is almost always backed up with a bank of
batteries so that the service continues to run in the event of an
emergency.
DSL is a data service that runs on the subscriber loop at the same time as
the voice service. This service is not required to be battery backed and
will invariably stop working when power is cut at the customer end point.
