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.
