Google lost data after Lightning in Belgium
Recently Google says that Data has been wiped out from one of its data centre in Belgium. This is unbelievable. As we know that Google is one of the big American multinational Technology Company. This is an unexpected news from Google. Although the chances of data being wiped by lightning strikes are incredibly low, users do have the option of being able to back things up locally as a safety measure.
Reason behind data lost & affect on Google Cloud data
According to some reports lighting on data centre strike two or maybe four time continuously. But the Google says that data has been wiped from the discs at one of its data centre in Belgium – after the local power grid was struck by lighting four time. Due to lighting on the local utilities grid (which power google’s European data centre) on 13th of August 2015, a brief loss of power to storage systems which host disk capacity for GCE instances in the europe-west1-b zone. Although Google system restored power quickly. Google already designed their system with battery backup so some of recent data already restored successfully. However, in few cases recent writes unrecoverable.
And Google also write “From 09:19 PDT on Thursday 13 August 2015, to Monday 17 August 2015, some Standard Persistent Disks in the europe-west1-b zone began to return sporadic I/O errors to their connected GCE instances. In total, approximately 5% of the Standard Persistent Disks in the zone experienced at least one I/O read or write failure during the course of the incident. Some management operations on the affected disks also failed, such as disk snapshot creation.” in one article.
Real Lost & The Google Compute Engine (GCE)
Some people have permanently lost access to their files. A number of disks maybe 5 or 6 damaged due to that lightning. However some already recovered and other will be. But the real thing is almost all data centres require more lighting protection than any other buildings. However lighting didn’t strike on actual data centre, but the local power grid. Justin Gale the Project Manager for Lightning protection service Orion, said “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.” he also added that the lightning could strike power or telecommunication cables which are connected to the building but at a distance and they still cause disruptions.
Google’s The Google Compute Engine (GCE) service allows it’s clients to store their data and also run virtual computers in the cloud. Google didn’t publish any report which shows that which clients data were affected, or what type of data was lost. In an online statement, Google said that data on just 0.000001% of disk space was permanently affected. But the company promise their clients that they will upgrade and improve their system so that its response procedures to make future losses less likely. However it is impossible to complete recover the data. A spokesman for data centre consultants Future-Tech, commented that while data centres were designed to withstand lightning strikes via a network of conductive lightning rods, it was not impossible for strikes to get through.
Google accepts full responsibility for the incident and says it is making upgrades to prevent something like this from happening again.
