Strangely, I seem to have lost my ability to connect to www.yahoo.com and www.google.com, and it seems to be a network settings or configuration issue I have with Mac OS X (I do not have this problem in Windows so it rules out the network, also this problem happens on multiple networks, i.e. WiFi hotspots). Can anyone tell me what got changed? It seems like there's an outgoing port block in the OS itself or something...

Below is an example from the command line of my inability to establish a connection to port 80 of www.google.com, as well as my success in connecting to www.apple.com.
