Amazon AWS: Some EC2 instances experienced connectivity issues and are now back to normal operation

According to Mars Finance News, on April 15, Amazon AWS released an update stating, "Between 12:40 AM and 1:43 AM Pacific Time, some EC2 instances in a single availability zone (apne1-az4) within the Asia Pacific Northeast 1 region (AP-NORTHEAST-1) experienced connection issues. The problem originated from simultaneous interruptions of primary and backup power sources, affecting the normal operation of related EC2 instances. During this period, customers might encounter higher error rates and latency on instances launched in the affected area, and some AWS APIs dependent on these EC2 instances may also be impacted. Our engineers automatically intervened within minutes and immediately began troubleshooting and implementing repair measures. We do not believe this issue will recur. Currently, only a very small number of instances remain deployed on hardware affected by the power interruption. We will continue to work on restoring all affected instances and volumes, but to achieve immediate recovery, we recommend replacing these instances or storage volumes that have not yet been restored. The issue has now been resolved, and services have returned to normal operation."
