We monitor our backup data center with an APC Netbotz 200 temperature/humidity unit. Our high temperature alert is set at 84F. Last night we received alerts that the temperature rose to 109F over 2 hours then dropped back to 82F after 4 hours. The data center is 1000 miles away. We were told by the hosting company that the temperature was being reported incorrectly.
1. What is the danger zone for high temperature for a data center?
2. Would an APC Netbotz give incorrect readings like this? See attached graph.
