LONDON – The company, which was hit by a major failure that caused many of the world’s top sites to go offline briefly this week, quickly blamed the problem with a software bug that was triggered when a customer changed a setting.
The issue of fast meant that internet users could not connect to a host of popular sites early Tuesday, including The New York Times, The Guardian, Twitch, Reddit and the UK Government website.
“We experienced a global outage due to an undetected software bug that surfaced on June 8, when it was triggered by a valid change in customer configuration,” Nick Rockwell, Fastly’s senior vice president of engineering and infrastructure, said in a blog post late in the day. Tuesday.
He said the outage was “broad and severe”, but the company quickly identified, isolated and disabled the problem, and after 49 minutes, most of its network was up and running again. The bug was included in a software update rolled out in May, and Rockwell said the company is trying to figure out why it was not detected during testing.
“While there were specific circumstances that triggered this disruption, we should have expected it,” Rockwell said.
San Francisco-based quickly delivers what is called a content delivery network – an event that allows customer sites to store data such as images and videos on various mirror servers in 26 countries. Keeping the data closer to the users means that they are displayed faster.
But the incident highlighted how much the global internet is dependent on a handful of companies behind fast, like Fastly, which provides vital infrastructure, and it heightened concerns about how vulnerable they are to more serious disruptions.
