It hasn't failed. I'm not sure the final outcome of the current debacle but there's still nothing that matches Heroku. I've been using it professionally for 6+ years now and it just works more than most other things I've used. It has its weird limitations but it's... Good. (And I've gone pretty deep into aspects of the buildpacks, how it stores its git repos on S3, and more.)
