i can access all the websites i want except facebook idk why , i called customer service of my internet provider he asked me to do alot of things , none of them helped and he asked me to trance the website so this what i got from it , i probably didn't understand anything so as i said whoever solve this will get 20m prize ^_^
ways i tried:-
1) reseting my router
2) clearing browsers cache
3)trying 4 diff browsers (chrome , firefox , maxthon , opera)
4) troubleshooting the internet connection
5) entering the site using proxy (this made it work but i want to enter normally)
