All the data from one of the data centres of Google in Belgium has wiped from the discs due to lightning. As a result of this, few people have lost their files. A number of discs have been damaged by lightning, but they were accessible after some time.
Typically, data centres require more protection from lightning as compared to the buildings. Four successive lightning strikes at the same spot are rare. But it happened in Belgium at Google data centre.

According to Justin Gale, project manager for the lightning protection service Orion, “The cabling alone can be struck anything up to a kilometre away, bring the shock back to the data centre and fuse everything that’s in it.”
The Google Compute Engine (GCE) provides the service to its client to store data and run virtual computers on cloud. Till now it is not known which data or client has been affected by the lightning. Google said that only 0.000001% data on the disk space is permanently affected.
According to Google, “Although automatic auxiliary systems restored power quickly, and the storage systems are designed with battery backup, some recently written data was located on storage systems which were more susceptible to power failure from extended or repeated battery drain.”
James Wilman, engineering sales director said,”Everything in the data centre is connected one way or another. If you get four large strikes it wouldn’t surprise me that it has affected the facility.” Though the data lost is low, but the users would not be able to recover it any ways.
