DNS failover?

Question

Domain Name System

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?

Answer 1

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

Answer 2

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.

Answer 3

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.
