Ahhh... I get those nostalgic moments from time to time, too. It's amazing when you go back to data centers you worked in/worked on in years past.

Life moves on, and so does technology. Data centers get bigger, smaller, containerized and modularized. They move to new cities where it's colder or there's water nearby or where power is cheap.

And just think, all of those new data centers will be someone's 'yesterday' quicker than you think!
