Armidale, NSW, Optus NBN

Same problem, started about Fri 3rd of June and has progressively gotten worse. I can usually connect fine, and depending on the population in the area it runs OK for a few seconds to a few minutes, but then nothing and 90k

I'm definitely thinking it is an Optus problem as I get the same issue tethering my mobile, which is also on Optus, but an old Telstra dongle works just fine. Also, for some reason the PS4 seems to work a bit better than my PC, and I haven't had an issues with other games (or websites, or streaming)... but they may be hosted more locally.
