Something doesn't smell right. Why are any voting machines up today? It isn't like there's an election just today?

Yes, air gapped means it's physically disconnected from the outside world.
In addition, if you wanted to maintain the air gap but wanted realtime aggregation of data you could use a device called a data diode which can write but cannot read, for example by sending data down a fiber optic with only a transmit line at the device and only a receive line on the reciever that plugs into the state network.

Last election I voted in was a checkmark on a piece of paper, and we knew the results by morning.
For me the issue is that they have to communicate to a central sever, which necessitates some sort of internet traversal, even if it is on a Peer too Site Virtual Private Network (P2S VPN), even a dedicated VPN appliance still has to go through the initialization process (IKEV1 and V2) which could be sniffed and cracked.
The machines likely rely on the backend severs to be able to function, and the backend went down and cascaded to the voting machines.
