wot bollox...
wot complete bollox!!! got on the unlimited hosting bandwagon too have they. They're a couple of years behind though, as many hosting companies have used this endlessly as a marketing ploy. You see, as any self respecting person who has any knowledge about hosting will tell you, diskspace and bandwidth are the least of you worries. What you're actually concerned with is resource usage of server ram/cpu. that's what bolloxs up a server (also disk i/o). So in theory, you may have "unlimited" diskspace/bandwidth, but in practice if you try to use up any sizable portion of that, you'll bring the server down (but before you do, your account will be disabled faster than you can say "exclamation mark"). The logic behind this business model for many hosting companies, is that the majority of customers will use their "unlimited" resources reasonably (i.e: the standard plans really, 1 gb diskspace, 20 gb transfer etc), and that only a handful of suckers will actually take "unlimited" at face value and proceed to royally bugger up the system. Hence those will be booted and told to bugger off else where, so that they don't ruin it for the other "nice" customers.
So you get a great marketing gimmick, lots of gullible customers, and kick out the ones that are really bothersome....brilliant....
