Google diagnosed a widespread outage that knocked out major services earlier this week, such as Gmail and YouTube, as a mistake with its system for identifying people online.

Alphabet Inc.’s Google has several tools that enable it to verify and track logged-in users. In October, the company began moving those tools to a new file storage system, and in the process misreported portions of the data, according to a Friday post. That caused several of its services to go down for 47 minutes Monday morning, a rare technical misstep.
