Seven years later, Cavern Technologies has shown it has made the most of that potential. Its latest, 60,000-square-foot expansion – set to be completed in December – will bring its total operating space up to 160,000 square feet. With even more space (up to 900,000 square feet more, Clune says) available for future growth, Cavern can have a new server room ready for any client that needs it in 45 days, compared to the typical year-long build period for a new data center.
