Nope, That Doesn't have a big impact on your rankings. But You Better Choose Better Offshore Hosting to provide value to your website. Better Load Time, Almost No Down Time.

What EGOL said and what Sebes said combined. If you want to run your affiliate links through an internal 302 redirect first (so that you can better track click activity) then that is a pretty well established process. You'd want to nofollow those links, of course. But cloaking? Nope. Don't even think about it. I recently had an issue where the developers put up a global header nav that used javascript. The JS was in a folder called /js/, which was blocked in the robots.txt file. Within an hour the site was penalized. google still showed the global header nav in their preview so I know they rendered the JS. My guess is after rendering they said, hey wait - the page Chrome/Browser rendered for our preview doesn't look like the page our standard Googlebot sees. They must be cloaking. Keep it simple and don't try to fool people who are a lot smarter than you. That's what I've learned over the years.
