Can't open Amazon.com in any browser

Those DNS servers are intended to be used to evade restrictions on copyrighted content. Such servers can never be trusted.

Please back up all data.

Unlock the Network preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Cllck Advanced and select the TCP/IP tab in the sheet that drops down. Near the top you may see this:

Configure IPv4: Using DHCP

If that's not what you see, stop here and ask for instructions.

Otherwise, select the DNS tab and delete all the DNS Servers from the list on the left by selecting them and clicking the minus-sign button below. Click OK, then Apply.

Open the DNS tab again. The server list should have been automatically repopulated with at least one address, and you should have normal Internet access. If so, you can close the preference pane. Otherwise, go back to the TCP/IP tab and click

Renew DHCP Lease

Check the DNS server list again. If it's still empty, enter this:

8.8.8.8

That's Google DNS, which I don't recommend for more than temporary use. Click OK, then Apply, and ask for instructions.

If you haven't you restarted your router and your broadband device (if they're separate) since you first noticed the problem, please do that now and see whether there's any change. Otherwise, see below.

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem.

Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.

The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Please double-click anywhere in the line of text below on this page to select it, then copy it to the Clipboard by pressing the key combination command-C:

amazon.com

Launch the Network Utility application.

Step 1

Select the Lookup tab and paste into the address field by pressing command-V. Then press return. Post the output that appears below – the text, please, not a screenshot.

Step 2

Select the Ping tab and do the same. Please enter the same input as you did in Step 1. Don't use the output of Step 1 as input to Step 2.

Important Note

Some web browsers and mail clients will automatically convert a domain name such as "www.example.com" to a clickable URL, such as http://www.example.com. That will interfere with the test. If necessary, edit the input in the Network Utility window to remove any added characters.

Any ideas on how to fix this??

FWIW, You didn't accidentally blacklist the site by any chance? If you are running anti-virus programs with a webshield they could erroneously block a site as well.

if you use Glimmer it can block a site from all browsers.

I don't know if this is related in any way or not, but when I go to Amazon.com on my Mac, the URL is www.amazon.com (no http://). I use Firefox. Would it be worth a shot to open Firefox, and then type www.amazon.com in the address bar just to make sure the appendage of the http:// isn't causing the issue?

Just a thought.

Cheers,

Also, wouldn't I be able to view Amazon in safe mode if it was a 3rd party blocking it? Can't see the site in safe-mode either...

I haven't used Glimmer in a few years. It's installed as a PrefPane and I don't know whether it works in Safe Mode or not.

What changed two days ago? Install a new program or update something?

Glimmer is a third party app so you would know if you installed it.

Could someone have entered the site in Parental Controls? There are very few ways a site can be globally blocked in all browsers simultaneously.

Interesting update though...

When I go to the raw IP (54.239.17.7) Amazon actually loads!

However, via the URL it does not.

Interesting indeed. It's as if the DNS server is not converting the URL to the correct IP number or your Mac is not sending it the correct URL from all your browsers. I have no idea how that could happen.
