Where's the Internet?

My laptop has been on for about ten minutes now and I have lost 7% of my battery. Also, I haven't been doing anything on it ever since I turned it on. So why was it on? I was trying to get on the Internet. I have a full connection, apparently, but it still takes the better part of ten minutes to actually get me on. In fact, I just opened my Itunes and listened to some music while I was waiting to get on the 1337 1|\|73|^[\]37. That got me thinking a little: Why is the Internet down sometimes? I've actually been thinking about this for a while now. This particular question irritates me a little because I don't like the thought of me shelling out my money for a service that doesn't actually work sometimes. Isn't my money going somewhere, like to the people who make sure it's always up and running? As my last-year's Agenda pad told me, the Internet can be compared with a Yo-Yo; It's sometimes up but mostly down.
