The two nodes I’ve been connected to have dropped almost exactly 40 mins
after the power has gone out, every time the power went out.  Definitely
would prefer to be on FTTH or FTTC so my NBN can run from the DC ups my
comms load at home runs from..

We rode on the winds of the rising storm,
 We ran to the sounds of thunder.
We danced among the lightning bolts,
 and tore the world asunder
