How much do CDNs really help?

Hi Damon,

I've asked my host (HostGator) about whitelisting IPs a couple times, and they said they did it, though they've been kind of "cagey" about it. I have no idea how to independently verify whether they actually did it.

Also, I think I may have caused the 502 errors by making changes without going into development mode (it's HARD to remember to do this; I'm used to being able to just make changes to my site). The problem is, once I start seeing them I don't know how to make them go away without shutting off CloudFlare altogether. Is there some way to quickly fix this if I accidentally make changes outside of development mode without shutting off CloudFlare?
