for such a site you don't need offshore hosting.. If you wish you to do the pinging, you need a hosting to provide you lots of IPs, because you need to rotate IPs when pinging. For your knowledge pingfarm is not doing the pinging, but you are. It uses a hidden iframe that calls pingomatic url to ping your links. So, pingfarm is not doing anything, but the visitor itself is. You need just a basic $5 hosting for that and no IPs required, no bandwidth...
I have a actual script that does the pinging though and my current host UnlimitedWebHosting doesn't allow it.
i see... huh, if you are on a dedicated box i don't think anybody will make a problem, as pinging takes really low bandwindth and there's nothing different than having a dedicated box with heavy trafficed sites.. do you have dedicated box with UnlimitedWebHosting?
well, on a shared hosting noone will let you do that, because it will eat cpu resource usage and networking usage.. get yourself a vps or a dedicated box is the best solution
