There’s some interesting things coming out of the bushfires royal commission; the last couple of days has highlighted the limitations of the emergency Triple-0 system, when surges in the number of calls outstripped available capacity, and overflow calls were put on hold, got recorded messages or were diverted.

The first half-hour of Jon Faine’s show on 774 is worth a listen for those interested, particularly the section from about 10 minutes in, with Garth Head, a former adviser to Minister for Police and Emergency Services. For geeks, it’s a reminder that sometimes the systems we design, implemennt and manage are sometimes critically important to those who rely on them.
