You can force a particular DNS to be queried like this:-
Does that help?
It may be that your server tries only a few by default, but if some go offline then it will go to the others too. What happens if you knowingly set the first two addresses to servers that don't offer DNS? Does a ping or nslookup still work?

The following is the scenario.

RESOLVER(5) File Formats Manual RESOLVER(5)NAME
resolver - resolver configuration file
SYNOPSIS
/etc/resolv.conf
DESCRIPTION
The resolver configuration file contains information that is read by the resolver routines the first time they are invoked by a process.
The file is designed to be human readable and contains a list of name-value pairs that provide various types of resolver information.
On a normally configured system this file should not be necessary. The only name server to be queried will be on the local machine and the
domain name is retrieved from the system.
The different configuration options are:
nameserver
followed by the Internet address (in dot notation) of a name server that the resolver should query. At least one name server should
be listed. Up to MAXNS (currently 3) name servers may be listed, in that case the resolver library queries tries them in the order
listed. If no nameserver entries are present, the default is to use the name server on the local machine. (The algorithm used is
to try a name server, and if the query times out, try the next, until out of name servers, then repeat trying all the name servers
until a maximum number of retries are made).
domain followed by a domain name, that is the default domain to append to names that do not have a dot in them. If no domain entries are
present, the domain returned by gethostname(2) is used (everything after the first `.'). Finally, if the host name does not contain
a domain part, the root domain is assumed.
The name value pair must appear on a single line, and the keyword (e.g. nameserver) must start the line. The value follows the keyword,
separated by white space.
