Incident History​

A DDoS attack targeted one of the IP addresses in our network, with traffic volume exceeding our capacity. Although this traffic should have been handled and scrubbed by our provider, the configured ACL allowed all traffic to reach the targeted IP.

On October 14, 2024, internet services via IIG and NIX experienced an outage caused by the upstream provider issue. Upon investigation, the upstream provider reported a double fault affecting both primary and backup network paths:

• Main Path: The upstream provider conducted planned maintenance under CR00025689 between JASMINE and THECLOUD from 00:06 to 00:06 (UTC+7) on October 14, 2024, rendering the main path unavailable.
• Protection Path: During the maintenance, a high-loss issue occurred on the protection path between JASMINE and THECLOUD from 00:06 to 00:20 (UTC+7), resulting in a simultaneous failure of both paths.

On October 7, 2024, a service outage occurred due to a power failure caused by a fire in the Power Distribution Unit (PDU) of cabinet BE04 at the Datacenter (CSL-TC). The incident disrupted multiple services.

On September 27, 2024, the Internet services via IIG and NIX experienced an outage due to an issue with our provider, JasTel. Upon investigation, JasTel reported a “Disk Full” alarm on the Electrical-Cross Connect (ECXC) card of the DWDM (Dense Wavelength Division Multiplexing) Node. This card stores critical configuration information for the device. The disk full issue led to a subsequent failure of the Transponder Card, which resulted in the loss of connectivity to the destination node and caused a circuit interruption, affecting our services on IIG and NIX.
