I was reading this article from Datacenter knowledge : Is Your Data Center Ready for the Summer? - Data Center Knowledge and it made me think we had our first taste of the summer some days ago here in Montreal. Heat inside a datacenter is critical and as you can imagine it is harder to cool a datacenter in summer when it’s 30 degrees (celcius) outside. At iWeb our datacenters are growing and filling up so fast that thinking about how our datacenters reacted to summer temperatures last year has nothing to do with how they will react this year. Well, so far so good, some air conditioning units reported errors and we already planned some adjustments but no real problem, our infrastructure team did a good job!
