nameserver 208.109.188.1 nameserver 208.109.188.2 –  arrowill12 Apr 10 '12 at 2:25
    
Are you using a proxy server for HTTP traffic? –  Wesley Apr 10 '12 at 2:27
    
At a terminal, type host s2plmirror01.prod.sdl2.secureserver.net –  Wesley Apr 10 '12 at 2:28

There is a problem with your DNS servers. 208.109.188.1 and 208.109.188.2 are GoDaddy default DNS servers. At the moment, it appears that 208.109.188.1 is not responding properly. I recommend changing your resolv.conf file to use another DNS provider. Perhaps OpenDNS: 208.67.220.220 and 208.67.222.222

EDIT 1

Try temporarily disabling iptables to test if it's a firewall rule:

/etc/init.d/iptables save
/etc/init.d/iptables stop

Test it and then restart the firewall:

/etc/init.d/iptables start

Edit 2

It was an iptables rule causing traffic blockage.

@user1272737 Try yum clean all –  Wesley Apr 10 '12 at 2:55
    
same error now with this after: Error: Cannot find a valid baseurl for repo: addons –  arrowill12 Apr 10 '12 at 3:07
    
@user1272737 Can you ping any internet address by its name? ping google.com or ping bing.com? What about ip addresses like ping 8.8.8.8 or ping 208.67.222.222? How about wget http://newark1.linode.com/100MB-newark.bin (just a 100mb file to test connection speed with) –  Wesley Apr 10 '12 at 3:20

Check your DNS server/configuration to see if it can resolve the hostname s2plmirror01.prod.sdl2.secureserver.net.
