DDoS attacks on sites in the Russian Federation. What to do?

Question

DDoS Protection

I see a simple solution. Raise mirrors that are only accessible from the Russian Federation , while leaving the old hosts for access from anywhere, if appropriate. Or do the opposite.
Explain if this will solve the problem for users from the Russian Federation, if so, why is this not done?

Answer 1

You need to understand how ddos ​​is organized, because of the hillock, ddos ​​can only be organized, but the attack itself may well come from local tails (viruses, funny mobile applications, etc.)
