Whilst many are enjoying the weather, some overlook servers hidden in server rooms, under stair cupboards, and boxes. Servers emit heat and whilst a modern system has more tolerant operating temperature ranges, sticking them in a small room with the door closed can cause them to generate heat and not be able to keep themselves cool enough. We hear of higher failure rates during the warmer months. Be mindful to keep the equipment cooler and you should not notice any break in service. If you leave your systems cooking during the heatwave then you may find that a hard drive could fail, a CPU could overheat and you lose service.
