YHK - yet another hacker news clone

There is also a new ATC system being rolled out, as early as today

It has been conjectured that the easiest way to locate a buried fiber optic cable is to start digging.

(The actual easiest method is to install the conduit or direct burial cable with tracer wire)

I don't quite understand this sort of thing happening. Wasn't the whole point of the internet to be a self-healing network where we route around severed cables, etc?

Or is it that these ATC networks are their own air-gapped network with less redundancy? That just doesn't add up. Or maybe there was only one line going to the ATC, with no multiple "ISPs" like a datacenter would have?

Pretty grim that a life critical system wasn't designed to report that the backup fibre is unserviceable until they attempt to switch over to it.

Wonder how long it was down before they attempted to use it? Days, weeks?

ATC seems like a great place to have redundancy with a starlink dish on the roof.
