I have put the nameservers into squid.conf. However, today I received the same error.
Squid times out on the following site https://www.skyplayer.com
This is the dig result:
[root@# dig skyplayer.sky.com

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> skyplayer.sky.com

If dig works and nslookup gives:
[root@]# nslookup skyplayer.com
Server:         213.171.192.249
Address:        213.171.192.249#53

Non-authoritative answer:
Name:   skyplayer.com
Address: 80.238.9.232

Any reasons why squid won't resolve it?

The server provides access to 650 campus users over a 1Gb link, with typically 100Req/s throughout the day. Our hope is that OpenDNS will reduce the time spent on ACL maintenance in squid, and allow us to drop some ACLs completely.
