In fact I don't think you can do that with DDoS attack easily. What I had in mind is more like a physical attack on switching equipment at a handful of branch exchange or backbone stations. That would require getting the network layout documentation, but IT sector in Belarus is enormous and well connected.

Yes there will be collateral of course, the most serious is to emergency response services who use the same network.

I realise it sounds a bit like that Death Star vent attack, but it is still more realistic than a Bluetooth mesh network that doesn't fold with more than a handful users.
