Using chrome, firefox, and safari gives me this type of warning: "Firefox can't establish a connection to the server at www.about.com". I tried checking the host through terminal and I get a response from about.com tells me ip etc. Also about.com works fine with iphone and pc at home on the same network. Firewall is off, and not having any issues with any other sites. I had little snitch at one point and uninstalled it. I tried connecting to my Verizon Mifi and am Getting the same error. Checked /etc/hosts and I get this which is normal from what I understand:
localhost is used to configure the loopback interface when the system is booting. Do not change this entry.
I even tried upgrading to Mountain lion and it didn't fix the issue. I'm not doing any sort of development on the machine so I have no idea what could be causing it. Any ideas?
Edit: Someone suggested it might be peer guardian blocking the site. I haven't turned it on in months, but I guess it might still be running something in the background. Will have to check later when I get home. Anyone have such an issue with peerguardian not being on and causing sites not to load?
