Wed 09 June 2021:
Fastly, the company behind a major global internet outage this week, says the incident was caused by a bug in its software that was triggered when one of its customers changed their settings.
Tuesday’s outage raised questions about the reliance of the internet on a few infrastructure companies. Fastly’s issue knocked out high traffic sites including news providers such as the Guardian and New York Times, as well as British government sites, Reddit and Amazon.com.
He said the problem should have been anticipated.

Fastly operates a group of servers strategically placed around the world to help customers move and store content close to their end users quickly and safely.
The company post gave a timeline of events and promised to examine and explain why Fastly had failed to detect the software bug during its own testing process.
Fastly noticed the outage within a minute of it occurring at 09:47 GMT, and engineers worked out the cause at 10:27 GMT. Once they disabled the settings that triggered the problem, most of the company’s network quickly recovered.
“Within 49 minutes, 95% of our network was operating as normal,” the company said.
Its networks were fully recovered at 12:35 GMT and it began rolling out a permanent software fix at 17:25 GMT, Fastly said.
