You know 2am is early and it's always fun to get a call at 2am. Over the years of doing this type of work I realize it's part of the business.
Hardware doesn't care what time it is. When it breaks, it breaks.
Right now is 4:15am and we have everything up and running. Just checking stuff and cleaning up the paper work. 99% of the employees will never know what happened and that's a really good thing.
