I'm one of the atypical users, when compared to the population at large, but probably in line for this audience.

Critical gear is on a transfer switch and both inputs to that come from UPSs that are on separate circuits. Less critical gear is fed from one UPS or the other to balance the load and allow headroom for a load shift due to a UPS failure. My office gear is on a separate UPS on a different circuit.

Thank you

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
