When I was involved in certifying new devices to get on a carrier network, the carrier insisted on exponential backoff as well as some randomness so you wouldn't get millions of voic..devices crying out at the same time when power was lost or restored.

It's not like this is a new problem, and it's been solved for decades - it's just good network design.

One example: This is exactly why randomness is required by Ethernet's ARP protocol: to avoid ARP storms when the power comes back on and all nodes try to get back on the network at the same time. (And ARP is still powering most IP connections (v4) today, since IPv6 is painfully fiddly by design, so no one uses v6 unless they have to...)
