Please help. The only site I can't get on is facebook, I have checked parental controls, Firewall is off...I have tried chrome, safari, firefox and tried via wifi in 3 different US cities. We were preivously in China using a VPN...but now in US and can't connect to facebook. All other sites are loading ok.
When I ping, I get this:
