Cold Weather and Network Performance

Today in Chicago it is below zero with the wind chill. What special preparations do you do to keep things running in cold weather?

Our main approach is keeping the people warm!  PTP800 IDU's tend to heat the enclosures enough for equipment ;).  We just got our field techs new bib overalls, coats, and hats.  That's the best approach to keeping your network running in this cold of weather, keep your employees running!
