Any idea where the VPS is? Countrywise that is. 'Cos if it's North Korea I think I can explain those download speeds. :|
London, a bit crap I know :C
Interesting... (or not)
Downloading over IPV6 works fine.
SCP upload to the VPS also fails after a small amount of data.
Your IPv4 settings don't have some strange non-duplexed options, or anything that could bog down the speed that aren't there on the IPv6 ones?
Found out I can actually get technical support even though I only paid a few quid. Looks like there's DDoS issues on the host.
Probably from North Korea.
Trying to prevent my competing missile program.
To be fair, with your 3D printer, you've got the technical advantage.
