DNS failover?

Our DNS zone is located at the Russian provider. Today he had problems with DNS. All of our resources were unavailable. This is the second time in a year.
How can DNS failover be organized?
Is it possible to somehow place a copy of the DNS zone with another provider, so that in the event of a fall in the main one, DNS requests go to the backup?
Maybe there are other solutions?

the solution for you is Amazon Route 53
- $0.50 per month in rent per zone
- plus pennies for requests

Yes, of course you can, for this there is a good master-salve scheme.
Slave server is configured in another DC. Slave will contain a copy of all master zones.
Let's say ns1.domen.ru is master, and ns2.domen.ru is slave, so if the master falls, then the slave will respond to all requests.

SDA + any foreign dns-provider.
Entries will have to be written by hand at two providers by hand.
Within one DNS provider, usually, a fault-tolerant scheme has already been built (it’s not in vain that registrars require “at least 2 dns servers and etc”). But providers occasionally fall entirely.
