Edit: ppcg.ga seems to become more popular now (but it WAS available when I posted this answer).
Ungolfed:
from webbrowser import * # Loads everything in the webbrowser module
open("http://ppcg.ga/") # Opens default browser to http://ppcg.ga/

Take that, ppcg.lol! (1 byte shorter)
Note: I added a separate answer leading to ppcg.lol, 'cause I've noticed the other sites doesn't work for me in Internet explorer 11, and I saw other users having this problem too.
