Was on Optus cable for quite a while. Was advertised at 100/2 but in reality was closer to 20/2 real world. Got NBN (HFC) the split second it was available. On 100/40 for the last year-ish and life is grand. Heh, eons ago I used to have two 56K dialup connections that I'd team into a Linux firewall. Good times. If AussieBroadBand offered faster than 100/40 in my area I'd probably take it (I have a mate on the far southside with 200/100 and he loves it). I hear they're considering offering higher down but lower up speeds, which I probably wouldn't consider. With all the uploading we do (cloud backups, remote links with lots of bidirectional traffic, etc) I wouldn't go backwards in my upload speeds. The 2:1 down/up ratio works pretty nicely for us.
