'Routing leak' hiccup briefly takes Google down worldwide

Lots of people are reporting on Twitter that they are experiencing issues with Google services.

The glitch occurred due to a ‘routing leak’ as per Doug Madory of Dyn Research. He states in a blog post that the routing leak occurred from an Indian broadband Internet provider which caused Google services to go down.

Routing leaks occur when a network provider broadcasts all or part of its internal routing table to one or more peered networks via the Border Gateway Protocol, causing network traffic to be routed incorrectly.

According to Dyn Research, an Indian ISP Hathway’s  boundary router incorrectly announced routing data for over 300 network prefixes belonging to Google to the Internet backbone via its provider Bharti Airtel.

“Bharti in turn announced these routes to the rest of the world and a number of ISPs accepted these routes.”

This caused the supposed routing leak which in turn took down Google and its allied services all over the world.

The leak is similar to a 2012 incident caused by an Indonesian ISP, which took Google offline for 30 minutes worldwide.
