That's similar to the total outage of all Rogers services in Canada back on July 7th 2022. It was compounded by the fact that the outage took out all Rogers cell phone service, making it impossible for Rogers employees to communicate with each other during the outage. A unified network means a unified failure mode.

Thankfully none of my 10 Gbps wavelengths were impacted. Oh did I appreciate my aversion to >= layer 2 services in my transport network!
