make sure to remove the code that tries to look them up from the AWS metadata:
config.compute_node_nameservers = ['1.2.3.4','2.3.4.5','3.4.5.6']
+ #require 'net/http'
+ #config.compute_node_nameservers = ['local', 'public'].collect do |iface|
+ # Net::HTTP.get(URI("http://169.254.169.254/latest/meta-data/#{iface}-ipv4")).match(/^[\d\.]+$/)[0]
+ #end << '172.16.0.23'
