I'm sure there is a reason for it but can they not be a little bit more specific?

Flight Service uses a different set of radios and can relay messages to ATC, but they've been slowly dismantled over the last two decades and wouldn't have the capacity to step in for an outage (nor should they be expected to - that's not their purpose).
Some aircraft have CPDLC for text-based communication, but it's asynchronous and you can't use that as a replacement for voice communication in the terminal environment. Also, many aircraft aren't equipped to receive it.
Pilots are trained on lost comms procedures, so if you're in the air and the radio fails they'd fall back to those regulations. Basically all the aircraft would fly their last assigned clearance, and attempt to deconflict manually with other aircraft over air-to-air radio (similar to flying into an untowered airport).

--- EDIT:
This could just be the first issue that's arisen -- the FAA announced it "is expanding across the nation" on Tuesday. Which could really mean anything.
FAA Announcement: https://www.faa.gov/newsroom/statements/general-statements
The Ars Technica article behind the Gizmodo one sadly doesn't have more info, either.
It'd be kind of absurd if a read-only integration took down nationwide infrastructure, but A) we've all been there... and B) the gizmodo article does mention they're also trying to phase out floppy disks for some jobs still, which tells me their CI/CD and rollback hygiene might not be top-notch. Hopefully the Real World contestant in charge of our transportation network is on site with a ClaudeCode terminal as we speak!
It does sound pretty deeply integrated, I will say:
SMART is a cloud-based system that centralizes 200 data streams – including weather patterns, flight paths, traffic flow, and controller staffing metrics – into one platform.
The fact sheet has two more vaguely worrying bullet points -- I would say such wild speculation is unwarranted, but I struggle to think what else could cause all the radios in the nation to go down at once... Emphasis mine: Creates **a single shared real-time picture** of schedules, weather, airport capacity, and airspace conditions.
...
Enhances the effectiveness of **existing** FAA air traffic management systems.nsoam 15 minutes ago | parent

And then "journalists" "feel" like they have to report on things because as long as they say they're reporting that "someone else had a feeling" they're not technically wrong, and they have bosses breathing down their necks to make the business work, to grow their monetizable audience.
And then no one knows what's true anymore, because we chose to be entertained instead of choosing to be informed.

"... ground stop is in effect for all destinations until further notice due to rolling frequency outtage in multiple centers..."
and
"... the ground stop is now a nationwide ground stop for all centers, all destinations until further notice due to widespread frequency outtages.. ..."

It looksl like the FAA started testing it in DC in September and annouced a nationwide rollout three days ago
This makes it seem more unlikely:
A team of FAA specialists in the SMART center in Washington, D.C., analyzes and validates the SMART data and provides scheduling recommendations to the agency’s Air Traffic Control System Command Center in Warrenton, VA. The Command Center then routes these recommendations to air traffic control facilities for local leadership to consider.
Of course, these may be the ATC analog of claude code approvals or they may be overstating the level of human oversight/HIL.cheesecakegood 15 minutes ago | parent

I am watching planes stacked up on final approach to land at KBOS as I type. From flight radar 24 they are a mix of foreign and domestic. So incoming flights are clearly being managed here.
Does this imply some potential risk from inbound international air traffic? Or maybe the FAA meant outbound? Something else I am missing?
