Amazon is back with an apology and an explanation for a high-profile malfunction that caused websites across the Internet to grind to a halt for hours on Tuesday. 192p3h

The online retail giant, which runs a popular cloud computing platform for sites such as Netflix, reddit and Quora, is blaming the outage on a simple - and perhaps somewhat amusing - employee mistake.

A team member was doing a bit of maintenance on AWS work properly.

When Amazon's Web Services Fails, Lots of People Get Wet

The cascading failure meant that many websites could no longer make changes to the information stored on Amazon's cloud platform. For everyday s, that meant being unable to load pages, transfer files or take other actions on some of the sites they regularly use.

"In this instance, the tool used allowed too much capacity to be removed too quickly," Amazon said. "We have modified this tool to remove capacity more slowly and added safeguards to prevent capacity from being removed when it will take any subsystem below its minimum required capacity level."

Translation: Employees will no longer be able to unplug whole parts of the Internet by mistake.

Amazon said it was sorry for the outage's effect on its customers and vowed to learn from the incident. One immediate next step? The company said it will subdivide its servers even more than before "to reduce blast radius and improve recovery," should something like this happen again.
