We have a main dns .123 server and a backup dns .789 server. All of our remote sites have 2 spots in the Cicso ASA router for DNS. We had the main dns .123 and the secondary DNS .789 in those spots . It was changed  so that primary dns.123 was our main dns server and then 8.8.8.8 for the secondary in case  our connection went down between us the remote sites could still work. They were divided up so some of the sites used our main DNS.123 server and 8.8.8.8 as the secondary dns and  some sites used our backup DNS.789 and then 8.8.8.8 for secondary.
Do you see any problem with this? I know there are some debates as to whether to use google dns or the ISP DNS, but other than that?
