NBN workers have been around my local area readying for a June 'availability date'.
On Saturday 19th, at 6PM there was a notified service outage for landline for up to 6 hours.
Last Thursday 24th, it came back on, > 110 hours later.
It seems the NBN 457 dudes managed to cut a main cable (According to the Telstra tech who found a 'new pair' for us, it appears to have taken them two days to admit to having done so).
We did get to enjoy ~26Mbps 4G in the mean time.
Now our ADSL2+ had gone from a solid (i.e. consistent) 5.9Mbps to a variable up to (at best) 3.9Mbps with occasional complete drop outs.
