I obviously host my proxies on my own servers, as I run a web hosting company, but where do you all find your proxy hosts? What kind of hosting do you use? Please let myself, and the rest of the members of this wonderful forum know.
Before we started our servers we used Intekhosting (http://www.intekhosting.com/proxy-hosting.php), was good.
I use a company for both my servers, one being a proxy and one for my clients www.webcs.com They are great and have helped a lot and always go out of their way to help
If you want reliability and control you can't go wrong with a VPS or dedicated server. In a shared environment you may run a small proxy but others may run large ones that could cause all sorts of problems on a server. Remember it takes just one site to ruin the hosting for everyone else. And considering most allowing proxy's have small operations they don't have the hundreds of servers to spread the load nicely and move sites around as demands change.
wdservers.com (thewird here on DP) Host 50+ proxies. Great hosting, fast, out permformed my last host, and is less expensive. Plus they have great experience hosting proxies.
