Power cuts - "resilient network" ain't a thing

Resilient network, see below, is how the internet was designed. Inter-connected so if  pathway A<>G was blocked the digi-postman could go by detour A>C>K>W>D> and end up at G, gasping "The mail must get through."
  • Once again the people of Central Otago get the rough end of the stick.
    High winds, hmmm... That's why god gave us anamometers and real time weather monitoring. Peak gust in Hawea 68kmh, which means that the biggest gust was officially in the high wind bracket, but the description of the average wind is strong breeze.
    When will Aurora stop blaming the weather for their incompetence and lack off maintenence.
    Yes trees blow over - no the company isn't usually responsible - but they are responsible for what happens next. Aurora have a regulatory obligation to trim trees clear of lines. Anyone think they meet that obligation?
    They also have a responsibility to build a resilient network. That means lots of interconnection points and the ability to restore power from adjacent areas. In Dunedin that happens. In Central Otago not so much.
    Sometimes it's as simple as having lots of break points, switches and links, along a line so that the affected area can be kept as small as possible. Once again, Central Otago is poorly served.
    But if you think Makarora has it rough spare a thought for Glenorchy. Although the wind there hasn't been above a mild breeze all day, if they want a hot lunch they will have to dig out the barbeque.
    Thanks Aurora, you've done out again.

    • John Evans Richard, four times within a week there were power outages in Portobello. My freezer will be stuffed
    • Richard Healey John which wouldn't be quite as bad if you could see an end to it or if the work that was being completed was indeed the most urgent that could be done. But you can't and it's not.

      The waste and inefficiency around this program of works is mind boggling.
  • John Evans There’s no end, this is the beginning. The financial rapists at the DCC snd their excessive borrowing for pet projects including stadiums with no return to the city, bus hubs with nompsssengers, traffic lights causing more pollution and walker friendly CVD with no way to park and get there.
