Trying the same test (downloading Control Ultimate Edition) from the Brisbane server at ~3pm rather than the dead of night gives the same download rate too. ~50MB/s.

After bumping the NBN connection speed up to 1000/50, and confirming that was effective (eg through speedtest.net), I've retried the download of Control Ultimate Edition.

Downloads from the Brisbane server are still mostly around 50MB/s, though the peak download rate was 72.7MB/s (very briefly).

Downloads from the Sydney server were mostly around 20MB/s, with a brief peak up to 43.7MB/s.

Downloads from the Melbourne server were mostly around 10MB/s, with a peak of 17.1MB/s. Seems like some kind of artificial restriction is in place now, though it could turn out to be something else (tcp buffer config of some sort maybe?).

Anyway, it seems like the local server (Brisbane) is now easily the fastest download for me, so I'll be using that from here on. Might as well drop the NBN connection back down to 400/50 as well, as there doesn't currently seem to be an advantage using the higher 1000/50 plan.
