hello people i have an simple question : is there any provider from wich i can buy an server with unmetred bandwith ? or at least 5tb monthly ? my budget is 200$ / month thanks..
Yes there are, you can look up http://www.webhostingtalk.com for the offers out there but $200/mth seems a little low for that much bandwidth but there is no harm checking.
Read the fine print too. Most unmetered servers in that price range have a bottleneck on your port speeds.
You may be able to make a special arrangement with your datacenter, most will give you unmetered bandwidth for about $40.00 USD for 1mbit (so a 10mbit unmetered port would cost...400 a month). It all depends on the speed your service needs, or if going to a capped account at a higher mbit rate would better suite your needs. I'd start by talking to your current host and see if they can make an arrangement, if not start looking elsewhere, as eddy2009 stated webhostingtalk.com is a good resource, but that 200 seems quite low. Price will also vary based upon the bandwidth provider (cogent, etc).
I think $200 is not good enough for unmetered or 5TB monthly bandwidth. You need to raise your budget significantly.
