(The actual easiest method is to install the conduit or direct burial cable with tracer wire)
And of course there are marker posts that say "buried fiber optic cable do not dig".
Before fiber a lot of things were put into the ground with no thought how you would find it again.
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?
* There is supposed to be a primary and a secondary link, in this case the primary failed and the fail-over also failed. It's unclear from the reporting if they were damaged in the same incident or if the failover was not tested or monitored adequately.
The Philadelphia TRACON site has been notoriously unreliable and was supposedly improved in 2025, it's also unclear if these issue actually could stem from that implementation.
That seems like an extremely foolhardy thing to do.
It seems like it would present a less-chaotic solution than that provided by having no data communications at all.
Pretty grim that a life critical system wasn't designed to report that the backup fibre was unserviceable until they attempted to switch over to it.
I wonder how long it was down? Days, weeks, months?
A lot of people are incompetent.

Russia has been staging covert operations and deniable provocations against European countries for many years. Since its full-scale invasion of Ukraine began in 2022 they have increased. These have included incursions by reconnaissance drones, hacking, arson, parcel bombs targeting cargo flights and plots to kill executives of leading European arms firms. In recent months the pace of such shadowy attacks appears to have risen again. The Russian operations have three main goals, according to analysts and security officials: trying to coerce European countries into halting their support for Ukraine; raising the costs of providing that support; and attempting to make NATO look powerless.

And of course there've been "suspicious" cable cuts in the Baltic Sea and other European waters ....

right. of course, no ones going to cut corners on the safe use of AI and secure infrastructure in this administration.
Sometimes the level of incompetence / lack of care in organizations like this astounds me. I understand issues like this can be complicated and systemic but it honestly makes me think very poorly of the technologists building these systems in government.
I worked for a regional ISP that had a major outage when the redundant fiber provided by the telephone company was cut in one place triggering a full loss of connectivity. It also caused a massive 911 outage for 200,000 people as it isolated the 911 center from the city core.
Turns out the phone company didn't connect one side of the ring topology even though they certified they did. Needless to say lawsuits abounded.
