Then behind that you'll have, generally speaking, backup diesel generators. Where the reliability question comes in is do you provide one generator or two. That's not an easy question to answer, because you have to look at the exact generators and the reliability on them, and you have to look at some of the other things that go into the system, what we call transfer switches and of course transformers and other equipment. It's very complicated to create a system with a high level of reliability, but it is achievable. Most brand-name providers do have that.
Exodus is a good example.
Generally, Exodus' facilities perform very well. In fact, the site that failed was actually acquired by Exodus in an acquisition. It had not yet been brought up to their level and been gone over by Exodus. In general, companies like Exodus and AboveNet have designed very good facilities with high levels of reliability and have worked very hard with the network providers to make sure they have the same levels of reliability on the network. So yes, I would make decisions about where I located my equipment because there are too many things that can go wrong if we end up in a prolonged period of blackouts with the backup systems.
