One Customer Broke the Internet

On Tuesday, June 8, 2021, web surfers around the world found themselves looking at 503 errors on many websites. As it turned out, one person broke the internet.

Major companies like Amazon, Reddit, Spotify, eBay, Twitch, Pinterest, CNET, BBC, CNN, and The New York Times all went offline due to a major 503 error on Fastly, a cloud computing service provider. A 503 error occurs when a server hosting a website is not ready to handle a request.

Fastly, headquartered in San Francisco, created their edge cloud platform in 2017 to increase cybersecurity, improve website loading times and bring websites and their attributes closer to users in other countries. But back in May 2021, Fastly deployed software that contained a bug that lied dormant until June 8th. One single customer accidentally triggered the bug which caused 85% of Fastly’s network to shut down. Even though Fastly detected the disruption in 1 minute, it took the company about an hour to have 95% of their network return to normal operations.

Fastly is taking actions to make sure an event like this does not occur again. They are deploying a bug fix across their network, examining processes that followed the incident, and evaluating testing processes and ways to improve remediation time. Experts are also looking into the dangers of combining many properties and services in a cloud platform on which many more companies rely on.
