On Tuesday (8), a global instability on the internet took down a variety of large sites. The crash was resolved the same day and late last night Fastly explained that the phenomenon was due to a bug caused by a single client configuration change.
“On May 12th, we began a software deployment that introduced a bug that could be triggered by a specific customer configuration under specific circumstances,” said Nick Rockwell, Senior Vice President of Engineering and Infrastructure. “At the beginning of June 8th, 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,” explained the expert on the company’s blog.

The customer’s name was not revealed, as was the request process the person made that resulted in the bug. But, according to the company, which is responsible for the content distribution service on the internet, “a permanent fix for the bug” was created and began to be implemented on the same day. In addition, the company’s spokesperson apologized for the inconvenience, as they did not foresee the possibility of the accident occurring.
“This outage was broad and severe, and we are very sorry for the impact it has had on our customers and everyone who depends on them,” Rockwell concluded.
