Our servers are all on 1GB networks which are very fast 500 – 900mbps, included in all packages.
You have choice to upgrade to 10GB port, which would give you a higher speed 1500-4000mbps! With this you would need to use dslreports or googlefiber speedtests to really see close to what your getting as there are no 10gb speedtests. This option is 50$ extra per month on any plan based in US for now.
Please do not rely on speedtest results. Make sure you’re testing in the location of where your server is.
