I had a shot at it here. Feel free to improve the wording if needed; English is not my first language.

Thanks, I accepted this answer as more generally useful IMHO, as @MadHatter's refers specifically to my case.

Thanks for the update. I reckon that if I asked instead about the parameters in which datacenter and consumer broadband differ, it would be more relevant to a sysadmin's job, so I will probably try with that.

Well, I guess that what I really wanted to know when I asked that question was, "How (in terms of what parameters) is broadband service that you get in a data center different than what you get in your home or small office". (I also made a wrong assumption about the price, but that only became clear to me AFTER you pointed out that home connections don't guarantee you data throughput - so, after a partial answer). Now, if you still care ;), do you think the above would be a valid SF question? If not, would it be more appropriate for SuperUser?
