I know that the FCC has a regulation since 2015 (47 CFR Section 9.20) requiring ISPs to provide an option to voice customers to purchase a battery backup for emergency voice services during power outages. As this is only an option and only applies to customers who subscribe to voice services, I was wondering if anyone had any insights on the prevalence of battery backup for home modem/routers? I.e., what percentage of home users actually install a battery backup in their home modem/router or use an external UPS?

Don't underestimate the disaster that is PG&E in California. We have a 
generator so don't really need battery backup for the router, but we're 
lucky since their DSLAM is battery backed up from the CO. Lots of cable 
users are not so lucky as they found out when PG&E started routinely 
having blackouts so they don't burn the state down. This shows why MSO 
should have the same mandate as telcos for battery backup to their headends.
