Excessive cold killed us once when the air exit vents froze shut. From: NANOG [mailto:nanog-bounces+david.hiers=cdk.com@nanog.org] On Behalf Of Naslund, Steve Sent: Wednesday, January 30, 2019 9:43 AM To: nanog@nanog.org Subject: RE: Effects of Cold Front on Internet Infrastructure - U.S. Midwest Ironically you don’t really save a lot of energy when it’s this cold because the loops are running at high speed and the humidification coils are working overtime to keep the RH up in the room. People think we can bring in all the outside cold we want but the issue then is humidity stability.
