My internet connection was down for about 14 hours.... the hub close to my house got spoilt in the rain or something like that.
We have a paper on Networking this semester, and this is the attribute about networking that I don't like - they tend to fail too often. In my opinion, computers and nature don't really get along too well. Make the hub waterproof, make the cables triple insulated, but there's not much you can do about 2 days of rainfall and the Crow that made a hole in the connector.
On a happy note, I'm now posting through wBloggar's new beta version v3.0b (I got access to it because I designed the logo in the forums :P ) and I have one word to describe it - wahoo! - it's really cool, I tell you.
