Asset pipeline broken after pushing to heroku - rails 3?

Question

I don't know what happened differently this time - my local env is running great. And my heroku app was running great. I pushed some code, and now it seems as if the asset pipline broke in my heroku app?

/assets/all.css and /assets/application.js both product "not found" errors now.

Any ideas what could have caused this or how I might be able to fix it?

To be clear - my app was working great yesterday. I didnt change the config in regards to the asset pipeline.

Answer 1

For future reference this was apparently a hardware failure for the day at heroku which they notified me of the following day, via email.

Answer 2

As ream88 said, you need the cedar stack to use Asset Pipeline. You need to create a new heroku project with --stack cedar option and modify your gemfile a bit.

I have a blog post on the subject. You can skip the compass/bootstrap stuff if you don't need it.
