nslookup works:

Non-authoritative answer:
Name:	mirrorlist.centos.org
Address: 108.61.16.227
Name:	mirrorlist.centos.org
Address: 84.22.180.89
Name:	mirrorlist.centos.org
Address: 88.150.173.218

but wget fails??

$ wget "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock";
--2015-12-08 08:04:15--  http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock
Resolving mirrorlist.centos.org... 199.187.126.90
Connecting to mirrorlist.centos.org|199.187.126.90|:80... 
failed: Connection timed out.
Retrying.

On my centos 6.2 box, wget fails also, but yum update works fine.
