AIS SuperNAT Incident: A Case Study in Internet Outage
On [Date], Thailand's largest internet service provider, AIS, experienced a nationwide outage that affected up to 100,000 subscribers. The root cause of the disruption was traced to a failure in the SuperNAT (Super Network Address Translation) system, a technology used to conserve IP addresses by allowing multiple devices to share a single public IP address.

Many businesses were forced to close temporarily due to their reliance on internet connectivity for operations. Schools and universities were unable to conduct online classes, and individuals were unable to work remotely or access essential online services.
AIS acknowledged the outage and apologized for the inconvenience it caused to its customers. The company quickly mobilized its technical teams to identify and resolve the issue. Within [Number of hours], service was restored to most affected subscribers.
