I have a 2008 iMac, OSX 10.9.5, 3.06GHz Intel Core 2 Duo with 4GB 1067 MHz DDR3
Everything has been running fine till recently.
In the past few weeks I have had trouble accessing or browsing some websites.
However, if I go through an anonymizer proxy web site, I can browse all previously unaccessible websites.
Anyone know what is going on?
TIA
Safari for Mac: If Safari can't open a website
Check the message that appears when a page fails to open. It may suggest ways to solve the problem or include information you need to solve it.
Make sure you’re using the correct address for the webpage. If you copied and pasted the address, make sure it doesn’t have extra characters or missing characters at the beginning or end.
If the website requires a VPN connection, make sure it’s functioning properly. For more information, see Connect to a virtual private network.
Try entering /index.html or /index.htm at the end of the address.
Choose View > Reload Page. If the page still won’t open, quit Safari, reopen it, then try again.
The website server may be busy, or the website may be unavailable temporarily. Try again later.
In the past few weeks I have had trouble accessing or browsing some websites.
Can you provide an example of one?
Which version of Safari are you using? Safari menu > About Safari.
However, if I go through an anonymizer proxy web site, I can browse all previously unaccessible websites.
This one?
Examples of sites I am no longer able to load/browse are:
www.zerohedge.com
www.stockcharts.com
The problem is not Safari because using other browsers does not solve the problem.
In the past 24h I seem to have isolated the problem to the router rather than my machine.
If I use a different router, my browsing goes back to normal.
Any suggestions as to how I can get the router to go back to normal?

The reason for asking which version of Safari you are using is so that I can use that version in an attempt to duplicate what you are doing, in an effort to solve your problem.
No matter though, if you isolated the problem to your router, then these are the possibilities: either the router's firmware is obsolete, or it has been altered from its factory configuration, or the router's settings have been modified to redirect name server queries to a host that is not providing correct results.
Fix them respectively by determining if newer firmware is available for your model router, or by restoring its factory default configuration (including firmware) or correcting its DNS settings. If the router is not capable of running newer firmware, or is obsolete and no longer supported by its manufacturer, then your only recourse is to replace it with a newer one.
At least one zerohedge IPv4 address is 54.87.181.187
For stockcharts, 66.150.15.92
Be sure to secure your wireless network with WPA2 encryption and a reasonably strong password known only to authorized users of it. The device itself should have its own password which can (and probably should) be different. The router as well as all your other network equipment must also be kept physically secure from unauthorized access. Also, it's best to not allow setup over WAN, otherwise known as remote setup or configuration over the Internet. The only reason for these comments is out of an abundance of caution, in the event unauthorized tampering may have occurred. From what you describe there is little reason for that concern, but those are fundamental security practices everyone should observe.
All my apologies and thank you for the long explanation.
My Safari browser is: Version 9.1.3 (9537.86.7.8)
Incidentally, mine is a Wi-Fi router. A hard reset has not solved the problem.
I will attempt to have the router replaced at the earliest.

So the router works fine will other computers.
So apparently the problem is between my iMac and the router with regards to these 2 specific websites.
I scanned the Apple help forums and have found people with similar issues. I am however either unable to implement the various solutions suggested or the solutions suggested do not work for my iMac
I tried to uninstall the router's settings by going through the "Open Network Preferences" option. I thought I removed the router in question and then tried to re-connect afresh to the same router. This procedure did not solve the issue however.
Is there a particular procedure I should follow in order to completely uninstall a router settings from my machine?
TIA
In Network Settings, click the Advanced... button, then the DNS tab.
What are the entries under DNS Servers?
For the router in question the entries under DNS are:
192.168.1.1
192.168.1.1
Thank you for the suggestions Eric.
No dice.
I tried to input the DNS numbers you suggested but the problem persisted.
I followed the link you provided and read about resetting the router to factory settings. I had already tried this with no positive results.
Still unable to log onto those two web sites

Shut down your Mac and restart it in "Safe Mode". To learn how to do that please read: Try safe mode if your Mac doesn't finish starting up. Determine if the same problems exist while operating in that mode, or not.
Then: Use the following procedure to determine if the problem is isolated to your Mac, or lies elsewhere.
Determine if you can open those two specific websites.
Restart your Mac normally and describe your results.
If the problem does not occur in either Safe Mode or in Recovery mode, but returns after restarting your Mac normally, please read If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support. The applicable section is "Remove Internet plug-ins and other add-ons" and the Support documents that follow "Learn more".
The problem persists both in Safe Mode as well as in MacOS Recovery mode.
The results are identical as in normal mode.
Safe mode took longer than 3 minutes to load.
After connecting to the router in question, I tried browsing the 2 websites that I have lost access to. The problem persisted.
Specifically, when trying to browse: www.zerohedge.com
The tab shows "504"
The message is: Gateway Timeout
When trying to peruse: www.stockcharts.com
The website loads
When entering ticker symbols I am unable to pull up the charts requested and it defaults to the standard DJIA chart
Using a different browser does not solve the problem
Connecting to alternative routers does indeed solve the problem
The tests you performed confirm the problem lies with the router. Nothing you do with the Mac will change that. The solution is to replace the router with a newer model.
Thank you for your time.
The company will not exchange the router because all their computers do work fine on it. Frankly, my laptop too has no trouble connecting to those two websites when connected to the same router.
Will have to carry on using the anonymizer.
Thank you all for your help
You're welcome. Knowing that you are using a managed network is important information.
Apparently your company has configured other computers to use a proxy server. If you wish, you can also apply those same settings to your Mac, but you will need to determine the proxy servers your company requires.
Unable to access some websites except through an anonymizer proxy
