[tor-relays] DNS resolving -problem?

[pa011]

Got problems overnight. On all servers traffic died down and looks like below - what went wrong please?
Here is what I did:

apt-get install dnsmasq

/etc/resolv.conf
	nameserver 127.0.0.1

/etc/dnsmasq.conf 
	server=216.87.84.211 #open.nic us
	server=84.200.69.80  #dns.watch us
	server=84.200.70.40  #dns.watch us
	server=194.150.168.168
	server=62.113.203.99
	server=188.165.200.156
	server=5.9.49.12
	server=193.183.98.154
	server=46.101.89.89
	cache-size=10000
	conf-file=usr/share/dnsmasq-base/trust-anchors.conf
	dnssec
	dnssec-check-unsigned


etc/init.d/dnsmasq restart

vnstat -h
