Tuesday’s Internet Outage Was Caused By One Customer Changing A Setting, Fastly Says

Fastly, the company hit by a major outage that caused many of the world’s top websites to go offline briefly this week, blamed the problem on a software bug that was triggered when a customer changed a setting.

The bug had been included in a software update that was rolled out in May and Rockwell said the company is trying to figure out why it wasn’t detected during testing.
