It's getting hot in here...
A former employer had a primary server room based out of their original site office near Old St. Lon. Based on the top floor of a an old building, the AC was a mish-mash of consumer office units which had a penchant for icing up and leaking all over the 'artistic pamphlet' photographic studio downstairs. During a particularly warm summer in the early 00's with 2 of the 3 units on the fritz, in order to get the temp back down to below 100 we took the decision to take the windows out of the server room partition to try to ventilate into the empty office which still had operational AC.
No server ops worth their salt should be without at least some skills as a glazier.
