Kazakhstan blocked major part of gmail functionality at one point of time. You couldn't download attachments, images didn't work, may be something else. I think they tried to block blogspot. but shared IP broke gmail. It was broken for months, nobody really cared except people pointlessly ranting on forums. Those, who needed working email, migrated to other providers or used proxy. I'd like to live in the world without censorship but I don't see this happening, so I'd prefer to minimize censorship damage at least.
