Facebook redirects

I get this every now and then, just with Facebook, no other web site. I use Chrome. Just now I tried to go to Facebook and was directed to Stock Market

Not sure what this is. I've found that clearing temp data doesn't help. I use:


ipconfig /flushdns
ipconfig /release
ipconfig /renew


and that works. A lot of the time I get to some site on akamai.net but this time it was that financial site. And Chrome didn't say I was being redirected. facebook.com evalutated to that site.

Any ideas why this happens? I know others on here have reported similar issues.

What I don't understand is how this behavior is entirely limited to Facebook. No other site.

The problems come and go. If I do the ipconfig /flushall thing it's OK, but why does this happen? And just with FB, nothing else.
