At this time of year, it not uncommon to experience ‘blips’ in the mains power supply. Not surprisingly these may be caused by weather related factors such as storms and high winds or the electricity grid switching to cater for increasing demand. If you have a UPS power supply, you will be protected and may notice your UPS alarming for one or two seconds, as it uses battery power to keep your servers and IT loads running. If not, then you may have witnessed a sudden computer crash, server reboot or experienced storage device damage.
