Denys, can you say anything about how these TSPU operate? I believe they at least swallow/stop TCP SYN packets toward some destinations (or across a link generally), but I'm curious as to what steps the devices take, to be able to judge impact seen as either: "broken gear" or "funky TPSU doing it's thing" thanks! -chris
And the drills do not mean at all "we will turn off the Internet for all the clients and see what happens", journalists trivialized it. Most likely, they checked the autonomous functioning of specific infrastructurally important networks connected to the Internet, isolating only them. It's not so bad idea in general, if someone find another significant bug in common software, to be able to isolate important networks from the internet at the click of a button and buy time for patching systems.
