In my life this country only became a 38/40 C (100+F in old fashioned units) in the last 2 or three years. On occasional brief peak to 35C was more normal. Yesterday we were at 39 / 40 for a few hours. The hair dryer breeze was quite the experience. I just went to sleep.
Anyway, after the data centre is designed with sufficient cooling and UPS capacity, 5 years later more kit has been added without consideration for the supporting infrastructure. How many times have I seen this? Lost count. The solution is often to choose some non essential stuff and switch it off, keep going like that until the only thing left on is kvm switch.
My local newspaper website is offline, probably because of heat.
