What happens if you type the address in, do you get the right site?

I'd normally says something was wrong with your bookmarks, but not on  
both programs.

Start Terminal (in Applications/Utilities) and type the following into  
the box:

host www.cnn.com

report what you get.

I get this:

dbdev2:~ johnson$ host www.cnn.com
www.cnn.com has address 157.166.255.19
www.cnn.com has address 157.166.255.18
;; connection timed out; no servers could be reached


Which means there's some networking issues going on, whether locally  
(to me) or at cnn or somewhere in between.

When I do:

host www.apple.com

I get:

www.apple.com is an alias for www.apple.com.akadns.net.
www.apple.com.akadns.net has address 17.251.200.32


17.*.*.* is Apples Class A network. One of the first companies to get  
on the Internet, and one of the few that has a class A network all  
their own.

Typing in www.cnn.com brought up Apple again.  A re-boot cleared up  
the problem for now.  I'll keep your eMail for future reference.

If a reboot cleared up the problem, then your local DNS cache was  
messed up, and there are terminal commands for fixing that:

In 10.5 it's:

lookupd -flushcache

On lower versions it's:

dscacheutil -flushcache


If it happens regularly, this could be something much more serious,  
something broken in your DNS settings or some sort of DNS spoofing  
attack.

Absolutely worst case scenario your ISP has been criminally negligent  
and hasn't updated it's DNS software to patch the horrible flaw that  
was discovered this summer, and they're being hacked.

Here is a good article on the 
subject:http://www.technologyreview.com/web/21537/?a=f 
  (use bugme/bugmenot for the username password.) that has the single  
scariest line I've ever read in an IT article:

I am speaking to you over an unsecure cell phone. Please do not ever  
say to anyone what you just said to me over an unsecure cell phone  
again.

Safari Firefox

2008-12-11 Thread George Hozendorf

I have www.cnn.com set at my home page, but is opens the Apple page.   
CNN is in my Bookmarks Bar.  When I click on it, I still get Apple.   
This scenario is the same in both Safari and Firefox.  Does anyone  
have any idea what's causing this?

Empty the Cache in each browser... see if your problem clears up.
