Few days ago, a global outage knocked out major services of Goolge, including Gmail and YouTube and on Friday (December 18) Google said that it happened due to a mistake with its system for identifying people online. It is to be noted that Google, which is owned by Alphabet Inc, has many tools which allows the tech giant to verify and track logged-in users. According to a post by Google, the company started moving those tools to a new file storage system and during this the system misreported portions of the data. The misreporting caused a global outage of Google services on Monday morning with several of its services going down for 47 minutes. Google said that this is a rare technical misstep.
