What will I need to run this kind of server?

[pacmanjones]

My speedtest.net results were Ping-10ms,Download-28mbps,Upload-9.18 on one computer, and Ping-27ms,Download-12.6mbps,Upload-9.16mbps (this computer was running much more). Both were tested with a wireless connection. Does this match with my "30M" plan?

Well, then according to Overlord, your upload is fast enough.

I am on a 50/10m connection and host fine for 5 people in minecraft and 20 people in ts.. Make sure you also have enough bandwidth.
