If you own a Web site (but also anyone else can find this useful) the above site shows how many other Web sites are being hosted on the same machine. The more sites, the slower your site might be -- depending on how much traffic the others get. I'm guessing that sysops try to distribute sites/server to get the traffic loads "equal." Don't know. But, here's how I used this tool today: I found out that one of my Web sites has to share a server with 20 other sites, and I found out that another server was mine alone...as expected since I pay for that exclusivity. So this is a way to check and see that I'm getting what was promised, and that I might want to move to another hoster to get less folks on my server. But wait, there's the best yet to come: On the server where I have to share now I have 20 other people to contact if the site starts to slow down or even goes down entirely from time to time. In other words, I can amass a "gang" to complain and not just be a schlub to my hoster who perhaps may ignore anything I request that costs him money. It's a democratic tool, see? I'd say this site is going to be shut down by hosters themselves or maybe some homeland security privacy men-in-black. Use it while you can. Anyone who sharing a server is open to having their "neighbors" approached for some hoster-political reason, and hosters are going to be threatened that their customers can be found so easily and then approached by a salesperson from another hoster saying, "Come to us instead of sharing a server with 20 others." Like that. Indeed, the whole size of the hoster's business can be "seen and plundered." Edg
