Amazon explains the outage that caused a large part of the Internet to be cut off

Amazon explained the web services outage that caused parts of the internet to go offline for several hours on December 7th — and promised more clarity if that happens in the future. as CNBC According to reports, Amazon revealed an automatic capacity expansion feature that led to “unexpected behavior” from intranet customers. Devices connecting that internal network to AWS have been flooded, causing connections to stop.

Amazon added that the nature of the failure prevented teams from identifying and solving the problem. They had to use the logs to find out what happened, and the internal instruments were affected as well. The rescuers were “too deliberate” in restoring service to avoid breaking still-running workloads, and they had to deal with a “latent problem” preventing network clients from falling back and giving systems a chance to recover.

The AWS department has temporarily disabled the scaling that led to the problem, and won’t restart it until there are solutions in place. Amazon said a fix for the underlying bug will come in a couple of weeks. There is also an additional network configuration to protect devices in the event of repeated failures.

It may be easier for you to understand crises next time. A new version of the AWS Service Status Dashboard is scheduled for release in early 2022 to provide clearer visibility into any outages, and the multi-region support system will help Amazon connect with customers much sooner. This won’t get AWS back faster during an incident, but it might eliminate some of the mystery when services go dark — important when victims include everything from Disney+ to Roomba vacuums.
