PowerDNS provides a neat way to implement GeoIP-based redirection and automatic failover. With GeoLite2-City database, it is able to select the closest mirror from a list of IPs we provide. Every 60 seconds it also checks if the mirror's HTTPS URL is working as expected; if that check fails, it stops giving it out (this acts as automatic failover).
