Decent speedtest app. Getting 20Mbit down and 30Mbit up from Australia which is probably about the limit of my office. It's a bit variable though. 200ms ping too which isn't great but that's about right for Australia-US connections. Absolute max is about 40Mbit/40Mbit but shared amongst a lot of people and it's middle of the day.

I have been noticing somewhat significant issues with bandwith to the US for other things (Yocto development in particular) but it doesn't seem particularly limited for this.
