Andrew Heckler Level 1 Level 1 (0 points)

Running 10.8.2 on a MBP 5,1. At first, I had no trouble. At some point, I became unable to access facebook from any browser- chrome, safari, or firefox. Chrome gives the response "This webpage is not available. Google Chrome could not load the webpage because www.facebook.com took too long to respond. The website may be down, or you may be experiencing issues with your Internet connection." i.e. the response I'd expect to get from any url without an internet connection. However, I can access Facebook just fine in Windows 7 via bootcamp and iOS. Other variables- I had a Facebook related extension called social fixer installed on chrome, but doubt this is the problem. Firefox and safari did not have the extension, and did not work either. In Windows 7, I kept the extension, and facebook still worked. I did a bit of research and really couldn't find much on this problem. Tried a few simple things, clearing cache, cookies etc., rebooting... no dice. Help appreciated! Thank you in advance!

    Just disable all the extensions in Safari first.

     

    Then, if you can get to Facebook, renable them one by one and test after each till you can't get to Fb anymore. Then you know the culprit.

     

    If after disabling all the extensions Fb is still unavailable, go to

     

    /Library/Internet Plug-ins

     

    and move everything out of that folder to a Temp folder on your desktop.

     

    Restart Safari and see if the problem's solved. If yes, move those items back in one at a time and test after each till the problem recurs.

    If you have the same problem in all browsers, then obviously it has nothing to do with Safari extensions, which can only affect Safari.

     

    Launch the Network Utility 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 Network Utility in the icon grid.

     

    Step 1

     

    Select the Lookup tab and enter

     

    www.facebook.com

     

    in the address field. Press return. Post the output – the text, please, not a screenshot.

     

    Step 2

     

    Select the Ping tab and do the same.

    Thank you Linc. Hopefully these tests can provide some insight.

    This is not a problem with Safari extensions, but thank you for trying to help.

  • Linc Davis Level 10 Level 10 (173,705 points)

    The DNS server that your router is using is sending back stale data, or the router itself is caching that data. Open the administration page of the router and look for its DNS settings. You should see one or more numerical addresses of the form "1.2.3.4". What are they?

  • Andrew Heckler Level 1 Level 1 (0 points)

    It says automatic from ISP- here's a look at it http://imgur.com/3tN0d

    Thank you again for your help Linc

    Then it's a problem with your ISP's servers. You can bypass them by entering the public DNS servers of your choice, either in the router (in which case all devices on the network will use them) or in the Network preference pane (in which case only that Mac will use them.) For example, you could use Level 3 DNS:

     

    4.2.2.1

    4.2.2.2

     

    That's an example, not an endorsement. There's a slight chance your ISP might block those servers, in which case you'll have to use something else.

    Here's a curveball- I also cannot access facebook when I use my iPhone as a hotspot, and thus from a different IP address (whether it's Wi-Fi, bluetooth or USB connection). Also, I couldn't access facebook via a different ISP (Time Warner) in Los Angeles, and I am now in Chicago on Comcast having the same problem. Which leads me to believe it's a problem with some kind of file(s) on this computer, and not an ISP failure. Let me know what you think. Thanks.

    Tried the Level 3 DNS example, no luck.

    Triple-click the line below to select it:

    /etc/hosts

    Right-click or control-click the highlighted line and select Services Open from the contextual menu. You may be prompted to confirm. A TextEdit window should then open. Please post the contents of the window -- the text, please, not a screenshot.
