Maybe datacenter companies could offer bare-metal cloud hosting. They rent out the servers and keep the hardware physically working, your devops team handles all the software aspects.
It is expensive, but not as expensive as something like heroku or aws for equivalent cores/RAM, and you get real hard drives.
In certain datacenters (think might be dallas05?) you can even get a 10Gbps uplink brought to a box so they have pretty big pipes available.
In Softlayer's Dallas facility (selected when ordering a server) 10 Gbps is an option.
The maximum amount of bandwidth available is 20TB.
Sometimes you can get more options by contacting their sales people directly instead of using the shopping cart.
