Somebody complained about the heat on the board* a while back, and the site lead said it was up to code. They have their network-wide internal standards. I forget what the ceiling for acceptable temperature is, but it gets pretty hot in the summer, especially if you're doing inbound. I don't worry about heat-related injuries or anything, but I wouldn't call it comfortable.

* What is it, Voice of the Associates? Something like that. It's a big whiteboard in the breakroom. You write down your login and a message for management/IT/HR and they write a response.
