Business Cable 20-100Mbit down/3-5Mbit up
It's usually against the TOS to use asymmetrical home use Internet Access like ASDL and Cable. Two of the main reasons are:
a)while the downlink has blazing speed, the uplink speed (control traffic outbound) is a small fraction of the downlink speed (you sitting there receiving web content for your own consumption). Since your major traffic on a website is outbound, your blazing speed is not so much so if you're running 8Mbit down/1Mbit up, your webserver traffic is limited to 1Mbit minus your personal needs.
b)the uplink channel can be on shared resources, so any one person hogging the uplink causes traffic degradation for all and this often is a major reason why hosting a public web server or ftp download server is prohibited in the TOS.
So, usually, the best way is to just face facts and go get a VPS (Virtual Private Server) which often has 100Mbit internet access without even asking. It costs a lot less than bringing in a high speed internet connection and paying the monthly fee for it.
