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

All the conventional telcos are far more focused on keeping voice

All true telco equipment is powered by batteries. Commerical power or
generators just recharge the batteries. No switch over when commerical
power is lost. Except when the generators(where equiped) switch over to
recharge the batteries.
Comcast and telcos do not put batteries in all remote

deal with the CPE, that the cable plant was the actual problem. The cable

moreso these days since IP has taken over everything. The need for reliable

Anyone else have issues where their IP block gets randomly set to China? We
have been trying to track down this issue for months and our customers are
starting to get upset. We get a /29 from our upstream provider that we CGNAT

I am a researcher working on developing a new switch-based on-the-fly
telemetry system that takes a flow chart as input to describe a
particular detection task (rather than just features or information
elements as in IPFIX). For an example of what I mean by "flow chart" see
the figure here:
Agreed, I’ve seen this before across wider boundaries. Even /22s.
