Web Server Speed

Hey I was wondering how hosting companies are able to provide 500kb/s upload speeds for file downloads? What is their connection called and how much does it cost roughly per month? Do you need to have a special location to use it? Anything related would help a bunch. Thanks.

Data Centers (hosting companies), cable and internet providers, and smaller communications companies buy large bandwidth pipes from the big telecommunications carriers like AT&T, Level 3, etc. These carriers come in multiple flavors including DS-X (Digital Signal) and OC (Optical Carrier) -n.

Digital signal carriers are supported by satellite or terrestrial based infrastructure and can carry data at rates up to 560Mbps per connection.

Optical carriers are supported by global, fiber optic networks with commercial speeds up to 2488 Mbps. OC-12 is a network line with transmission speeds of up to 621.84 Mbps, used by many ISP's and WANs and commonly used by mid-sized web hosting companies.

Usually the major providers only have connections in major cities. Regional ISP's and telecommunications commonly sell DS and OC connections to distribute them out over a wide area but generally they cost more. If you're interested in this, my advise would be to call up your telecommunications co. and tell them of your needs. Careful as these connections are very expensive. DS3 cxn's start at around $2,000/mo. whereas OC3 cxn's will run you around $20,000/mo. If you plan to hang with the big boys, then a reliable OC12 cxn will run you upwards of $300,000/mo.

Usually you start with multiple T1/Cable lines and scale up to meet bandwidth needs as your customer base and revenues grow. In some cases telecommunications co.'s will sell fractions of DS and OC connections for a discount price. Its not like upstarts just go out and buy one of these connections... unless you have a lot of venture capital to burn.
