Seems a batch of sites got unblocked. Wiki.edia (marvel as I blog in regular expressions) is accessible (again), Wikibooks, Reuters, CNN, and a lot more.
Still blocked: blogspot, livejournal, wordpress (no surprise here -- lots of political blogs), BBC, certainly more; most importantly, Sinfest and CRFH :-( (why the f* is CRFH blocked? Zombies? Satan?)
Also, the web feels slightly faster in general!
