If I was you I'd just rent a server from ovh.co.uk / kimsufi.co.uk / hetzner.de/en and use a CDN. I am basing on your performance requirements that this is not a local gaming service. The advantage you have is you can upgrade to new hardware every year and the hardware is not your problem.
OVH is building one of the most advance networks with over 1tbps. Their 10gbps servers can actually push 10gbps which just gets me really excited.
