add more DNS servers in /etc/resolv.conf file. They will be probed in order of appearance in case of failure. As in :
# the ones you're using primary :
10.101.1.5
10.101.1.6
# and then the backups :
192.168.2.1
192.168.2.2
# As a side note - it's recommended by RFC that DNS servers should not reside in the same subnet, in case of network failure.

UUID(3) 							    Libuuid API 							   UUID(3)

NAME
uuid - DCE compatible Universally Unique Identifier library SYNOPSIS
#include <uuid/uuid.h> DESCRIPTION
The UUID library is used to generate unique identifiers for objects that may be accessible beyond the local system. This library generates UUIDs compatible with those created by the Open Software Foundation (OSF) Distributed Computing Environment (DCE) utility uuidgen. The UUIDs generated by this library can be reasonably expected to be unique within a system, and unique across all systems. They could be used, for instance, to generate unique HTTP cookies across multiple web servers without communication between the servers, and without fear of a name clash. CONFORMING TO
