There are situations when the primary DNS server (first server entry found in resolv.conf) mentioned in /etc/resolv.conf of the client DNS machine, is down and the client is still trying to communicate through the primary server. In such a situation you can quickly reorder the DNS server list to avoid DNS lookup delays.
