I'm just a student going about my online classes then suddenly, out of nowhere most of the websites I use suddenly got blocked. I don't know why this happened. I know it's not my parents who blocked the websites as they have provided me this pc (mac) so that I can use it for class and also for my pass time. So please, I really need help because I can't access some of my school files because websites are being blocked by cisco. Maybe someone remotely blocked the websites possibly a troll but more likely to be a mistake by someone else.
