Internet censorship

I wasn't sure how countries whose intent it was to censor internet content went about it:

"In February last year, Pakistan Telecom began routing the prefix 208.65.153.0/24 to a null site inside Pakistan. This routing message was then forwarded to the rest of the internet so that all traffic to 208.65.153.0/24 ended up in Pakistan. That turned out to be bad news for YouTube which owns the prefix and which was more or less unnaccessible during the hijacking of its prefix. The 28th February has since gained some notoriety for being the date of one of the most serious prefix hijacks in history."

I'm sure that there's a workaround for any conceivable censorship methodology, in this country at least.
