> after 2 days both the cable internet and cell towers went down, so even 5G would not have helped.

I discovered the same thing the hard way myself recently (in Norway); turns out that cell towers only has enough battery for ~24-36 hours (if you're lucky).

However, someone messing with the fibre to my house is a bigger possibility than power outage, so I'll probably end up with this 5G product. :)
