Because even 2000-2500 hosted Sites will surely and rapidly kill a server, so we do not offer UnlimitedDomain Reseller plans. But you can still host quite a few...and diskspace+bandwidth are very decent also.

To keep the servers stable and our clients happy, we decided not to play with fire by offering something that is technically unsustainable i.e. UnlimitedSites per Reseller Account.

We have **real** plans available on our site and have been web hosting since 1999. We own our hardware colocated in XO.com Fremont, Datacenter and have access to true Bandwidth.

Here is the link to Linux plan...

2 Gb disk + 30 Gb Bandwidth + Host 25 domains is $20/month

Addon Domains are also an available option if you need to exceed 25 hosted domains in near future.
