Does disabling NetworkManager-controlled dnsmasq fix the problem? (To disable NetworkManager-controlled dnsmasq, comment out "dns=dnsmasq" in /etc/NetworkManager/NetworkManager.conf and then restart network-manager.)
Hypothesis: dnsmasq is given two nameserver addresses. The first nameserver listed, which is the one always consulted first if dnsmasq is not used, functions correctly. The second one malfunctions. Dnsmasq sometimes consults the second one and therefore sometimes returns incorrect results.
