Consolidate EC2 hosts

I’m trying my best to use as less EC2 hosts as possible, and seems I successfully made all of my stuffs running on … one micro instance 😀 .

Actually it surprised me a little thinking that I was running 2 large, 1 small, and 3 micro back to last September, obviously I spent too much on “playing” 🙁 .

Now I’m waiting all crawlers heading to the new machine, I found some crawlers are really … stupid? They didn’t move to the new machine even after the DNS had been update for more than 12 hours.
