YouTube - My main income stream went off line

My main stream of income comes from a site that is full of YouTube videos. I noticed one evening that the money wasn't coming in at all so I decided to investigate. Upon my arrival at YouTube.com I was viewing a white screen with the simple phrase "Service Unavailable". I was shocked to say the least. My main stream of income was unavailable and no explanation of why. Luckily the site was down for only around 6 hours and most of that time was through the night. I can say that I learned an important lesson in all this. I even asked myself some questions.
First, I didn't have a backup plan. What if the server totally died? It could take weeks to get up and running again.
Second - Should I strengthen my other streams of income?
Third - Should I offer more then just video content?
Forth - Should I switch my video host?

I believe Youtube is the best video hosting site out there. I want to thank them for all the work that they do. From the lesson I learned, there is some steps I should take to prevent any future problems. I will be hosting my videos at another video hosting site, this will be a backup incase YouTube goes down for a long period of time. I do have my online focuses for my income. With that said, there is always room for improvement thought all my online income endeavors. I will now be putting in more time to grow and develop multiple streams of income.

I do depend on Google for almost all my online work. (Blogger, Adsense, FeedBurner, Analytics, Alerts) It is not just my video hosting that I should be developing backup strategies for. If one of those elements goes down I have no backup plan in place. Wow, I am scaring myself just writing this post. I am going to start my backup plan. Let me know what you do.
