The results will now be presented to President Putin.
Experts remain concerned about the trend for some countries to dismantle the internet, but no one really can deny the fact that while the internet has opened up a lot of information channels and freedom of ideas, it has been also abused and used to destabilized and revolutionized countries and public safety.

"The results of the exercises showed that, in general, both the authorities and telecoms operators are ready to effectively respond to emerging risks and threats, to ensure the stable functioning of both the internet and unified telecommunication network in the Russian Federation," said Alexey Sokolov.
The state-owned Tass news agency reported the tests had assessed the vulnerability of internet-of-things devices, and also involved an exercise to test Runet's ability to stand up to "external negative influences".
If the grass is greener on the other side, you can bet the water bill is higher.
