home router battery backup

Wed Jan 12 17:35:19 UTC 2022

Hi NANOG mailing list,

I am a graduate student, currently conducting research on how power outages affect home Internet users. 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?

Thanks.
Scott
