safari can't access specific sites or load infinitely

i have a problem with safari

from yesterday, i can't get in some specific sites including apple korea.
safari load those sites very long and display weird pages lack of images or something like those stuff.

but the other computer on the same network can access to those sites.

to give you more information, my macbook access internet through airport express. and i emptied cache and reset safari. but it keeps out of working properly.

what should i check for to fix this ?

it was dns

i found out what causes it. it was dns setting.
it seems to be a something wrong with google dns 8.8.8.8.
after i delete that dns address, safari has started working properly.
for those who have the same problem, this thread will be kept without deleting.
