I’m Kevin Heslin, editor of Mission Critical magazine, and welcome to a new ES blog. If you have been reading ES very closely, you might have noticed my name on the masthead and wondered whether I might be soon start pulling my weight. ES editor Robert Beverly wondered something similar and asked if I would start blogging on mission critical topics. How could I refuse such a generous offer?I’m very grateful to Robert for offering me this forum. I’ve been looking for a good place to share a lot of the information I develop about mission critical facilities at tradeshows and in conversations with people who design, build, and operate data centers and emergency backup facilities. I’m planning to post next week fromNGDC andDatacenter Dynamicsshows on the west coast.
