To Catch A Dyno Thief

James Somers takes down my web host, Heroku:

In fact a routing layer designed for non-blocking, evented, realtime app servers like Node and its ilk — a routing layer that assumes every dyno in a pool is as capable of serving a request as any other — is about as bad as it gets for Rails, where almost the opposite is true: the available dynos are perfectly snappy and the others, until they become available, are useless. The unfortunate conclusion being that Heroku is not appropriate for any Rails app that's more than a toy.
