Earlier, a serious failure of AWS, Amazon's cloud computing service, affected thousands of large websites. At that time, users were unable to access these websites. The companies belonging to the major websites also suffered operational losses during the interruption, and the compensation provided by Amazon was basically meaningless.
Later investigations revealed that the failure occurred in Amazon Route 53, a large-scale DNS system launched by Amazon and located in a data center in Northern Virginia, USA. This DNS system manages tens of millions of DNS records. Due to an internal system failure, empty DNS records appeared, and the automated system did not solve the problem.
To avoid similar issues from happening again, Amazon is now launching a program called Amazon Route 53 Accelerated Recovery, which promises a recovery time target of 60 minutes during service outages and enhancements that ensure customers can continue making DNS changes and configuring infrastructure during regional outages, providing greater predictability and resiliency for critical applications.
Amazon's senior solutions architect said that customers do not need to learn APIs or modify existing automation scripts to use the Route 53 accelerated recovery function, and do not need to wait for the service to be fully restored, so that customers can quickly adjust themselves after a critical failure of Route 53.
Of course, the service itself is used as a backup service, and Amazon is not prepared to charge extra. The accelerated recovery feature for Amazon Route 53 public hosting regions is already widely available and free to use, but this feature is not supported in private hosting regions.
