They have installed devices called "TSPU" on major operators.
Isolation of specific networks is done without changing BGP 
announcements, obviously.
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.
