Disruption by a file
Nick Rockwell, Senior Vice President of Engineering and Infrastructure wrote the blog post titled “summary of June 8 outage”. Rockwell said,
“We detected the disruption within one minute, then identified and isolated the cause, and disabled the configuration. Within 49 minutes, 95% of our network was operating as normal.”
Fastly began a software deployment that introduced a bug that could be triggered by a specific customer configuration under specific circumstances, on May 12. “Early June 8, a customer pushed a valid configuration change that included the specific circumstances that triggered the bug, which caused 85% of our network to return errors,” according to Rockwell.
