My particular server room doesn't seem to have had a problem with static

You are obviously wearing the right shoes!!

Static is a funny thing. I have been at a loss to explain sometimes why certain settings get lots of it and others don't. Also, given the amount of attention that is paid to static-related equipment damage, my guess is that the actual overall amount of damage due to static is pretty low -- just my impression, and, if true, may only be true due to improvements in systems like climate control. OTOH, I would not want to be the one poor b*stard who has to explain that a $50,000 switch processor has just gone bad while caught not wearing a grounding strap!
