Guys you can also try cloudflare, their pro plan is awesome (on top of caching and distributing your content from multiple locations they can also optimize images, implement js hacks from their side like lazy image load, preloading the page before the media content, etc. etc.). I have a dedicated server + nginx + this for my biggest site, and I can say it's awesome, handling #*$!,#*$! visitors per day with a ridiculously low cpu usage (+ this server serves a lot of static content at the same time).
Plus it doesn't seem to affect google rankings, I use them for months and everything is fine.
PS: I'm not a cloudflare rep :D
