Macbook Pro won't connect to Facebook & other websites

[Propellerbook]

Okay, so I am running on a Macbook Pro OS X V 10.10.3, 2.2 HGz Intel Core i7.

Every single website works just fine except www.facebook.com & www.propellerhead.se.

Things I've tried:
Clearing cache, cookies, history
Updating software
Restarting the computer
I've even gone as far as doing wacky things like clearing out Java and Flash Player settings

Nothing's fixed this issue. It doesn't work on Chrome, Firefox, or Safari.

Does it work on other devices connected to the router

I have seen certain websites denied access and its been a problem on the router - switching the router off for 10mins usually fixes it
In fact 100% of the time this has resolved the issue

Can you also be specific to what exactly doesn't work?
Page doesn't display?
Won't log in?
Etc

Is your MacBook on a VPN connection or something like that? Check the settings in System Prefs, Network.
