I know this is not the point of your comment, but which Georgia specifically is the right target to bomb?
The one in Caucasus is supposedly friendly, South Georgia is British property so allied land, and, eh, the remaining one is, as I understand, the always wrong one to bomb.
There is a technology called BLE, which together with mesh networking and synchronization of messages instead of routing them can give you connectivity in the middle of big events, without too much signal noise.
Of course other than Briar and that Bitchat thing I don’t know what to use in such situations.
