Okay in fairness.... Telstra pulled out all stops on this one. VERY impressed.
3PM yesterday - internet drops completely and my testing indicates fibre outage.
4PM yesterday - call Telstra and the tech actually listens when I mention I'm in IT. Runs a port check, port reset, and then checks on their end and gets some wacky attenuation stats indicating a fibre fault. Agrees with me the fault is outside our house and on the WAN side of the NBN NTD. Organises for NBN contractor to attend between 1 and 5 pm today.
1PM today - nothing.
4:50PM today - called to advise tech is running late and will be here around 7PM.
7PM today - tech rolls up. Runs a series of tests and confirms the attenuation is WAY out of guidelines. Does some more testing, heads to the node, pulls my fibre cable and cleans it. Heads to the pit, notices fibre joiner slightly disconnected and fibre is dirty so cleans it. Heads to side of house and checks box, cleans fibre regardless. BOOM up comes the fibre working a treat, and back to normal operations and speed.
8PM today - tech leaves and heads home.
