Contrary to the popular saying that lightning never strikes twice on the same spot, Google's European data center located in Belgium was hit by lightning four times on Tuesday August 13th. While some files were temporarily lost, others are permanently erased. In particular, according to a Google report, 5% of space on the disks underwent temporary failure whereas 0.000001% of disk space was permanently damaged. This data center powers a service known as Google Compute Engine, used by business customers who rely on Google's colossal servers to execute high-powered computing activities. Therefore no consumer oriented services, such as Gmail, YouTube or Drive were affected. "We have conducted a thorough analysis of the issue and we are working to improve these to maximize the reliability of GCE," Google claimed. "We apologize to all our customers who were affected by this exceptional incident."
