[nznog] Are Telecom Micro Outages still an issue?

HI all, Have been racking my brains trying to solve a problem, and I suddenly remembered an issue that Telecom had regarding "micro-outages". Does this problem still exist? Our problem comes up with a customer using chat rooms in the Moodle Learning Management System, for students in remote locations. The chat room relies upon a persistent socket connection for the duration of the "chat". Perhaps for 30+ mins or so at a time. However students and teachers are regularly dropped. The Chat daemon is basically a socket server, and the only way I can see this happening is if the socket connection is broken. We do not see this effect in LAN trials. kind regards Gary Benner Ref#: 41006
