There is no better place to see first hand how much things have changed since the dotcomm days. I recently visited our ISP’s co-location facility. Man, that place is like a ghost town. A large lobby with just one attendant! If you are not careful you’ll miss him. You get your access approval from him and find your way through several doors and corridors until you get to your servers. Its cold and empty!
I remember the days when the same facility was packed with people and machines. In those days, if you were not careful you could easily mess up the neighboring servers. Today so many cages are empty with no machines whatsoever. There is an eerie silence and emptiness that is almost frightening.
