Makes sense. CNN reported that international airlines were still departing for North Atlantic flights, apparently because they use a separate communications system.

Yeah, oceanic flights largely use satellite-based CPDLC today, or HF voice as a fallback, but not VHF in any case (which I suspect is the implicated system here).

VHF Omnirange (VOR)[1] is unlikely to be involved. VOR stations are not dependent on a network. All they need is power. It's 1950s technology. The big ring of antennas next to US 101 just north of SJC is a VOR.

		Sorry, typo, I meant VHF (i.e. voiceband), of course. VORs are indeed for navigation, not communication. Updated.
