I get a "Server denies connections".....it seems totally random with the biggest ones being Google and Facebook, even 'Down for every one or just me?' won't work.
I've tried turning off all my extensions, deleting my preferences.plist, flushing my dnscache & so far nothing has gotten the problem fixed.
It just started yesterday and I've been running ML since it was released at the end of July.
I know it's something specific to my Mac Pro because both my iPhone and my wife's PC work just fine on my home network.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window:
curl -I http://www.apple.com
Press return. You should almost instantly get several lines of output below what you entered, the first of which begins with something like this:
If there's no output within ten seconds, consider that a failure. You can then quit Terminal. Post your results.

Odd, I don't ever remember my terminal prompt starting with "localhost"

Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with networks that require any kind of authentication other than a WPA or WPA2 Personal password.
From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Test. After testing, reboot as usual and post the results.
