My first question is how this works when you have more than one server. It's not mentioned in the article, but this implementation uses the standard Rails Cache: https://github.com/kickstarter/rack-attack/blob/master/lib/rack/attack/cache.rb https://github.com/kickstarter/rack-attack/blob/master/lib/r... There are particular hooks in there for Redis. So if you've got "n" servers, it seems the preferred approach is to use a central Redis store.
