One Fastly Customer Triggered Internet Outage

A major outage has affected a number of high profile websites including Amazon, Reddit and Twitch.

One customer changing their settings had set in motion a major internet blackout, Fastly said.

The UK government website - - was also down as were the Financial Times, the Guardian and the New York Times.

Other websites knocked offline included:

- PayPal

- Shopify


- HBO Max

- Vimeo

A major internet blackout that hit many high-profile websites recently has been blamed on a software bug. Fastly, the cloud-computing company responsible for the issues, said the bug had been triggered when one of its customers had changed their settings. The outage has raised questions about relying on a handful of companies to run the vast infrastructure that underpins the internet.

Fastly apologised and said the problem should have been anticipated.

The outage, which lasted about an hour, hit some popular websites such as Amazon, Reddit, the Guardian and the New York Times. Fastly senior engineering executive Nick Rockwell said: "This outage was broad and severe - and we're truly sorry for the impact to our customers and everyone who relies on them."

The hashtag "InternetOutage" was soon trending on social media as more and more broken websites were discovered.

The problem had been spotted and rectified within 50 minutes, Fastly said.

The company operates servers at strategic points around the world to help customers move and store content close to their end users.

But a customer quite legitimately changing their settings had exposed a bug in a software update issued to customers in mid-May, causing "85% of our network to return errors", it said.

Engineers had worked out the cause of the problem about 40 minutes after websites had gone offline at about 11:00 BST, Fastly said.

"Within 49 minutes, 95% of our network was operating as normal," it said.

The company has deployed a bug fix across its network and promised a "post mortem of the processes and practices we followed during this incident" and to "figure out why we didn't detect the bug during our software quality assurance and testing processes".


This may actually be a lesson to those hosts who like to customise everything within their platforms and control panels. It can become so over customised that these types of errors can, and will occur. Take the likes of Godaddy, DreamHost and Blue Host to name a few. They seem to love customising everything making it harder in fact for a customer not used to that tye of panel to navigate their way around. Maybe it is best to select a host that uses a panel which is much more mainstream such as cPanel. At least you can move web hosts with ease if you needed.
