Sorry, I should've specified; Sky tech. support apparently ran tests while I was on the phone and he "guessed" at 12.5mbit. Just resynced now... lost about 80kbit on the upload and gained 200kbit on the download (I'd rather it the other way around!), however a quick speedtest reveals much slower speeds than I was acheiving earlier (I was getting a solid 8.9mbit, peaking realistically at around 1.09mbytes/sec at around 1800.) but now it's down to around 7.3mbit at 0200!
