title: Perfectly working Heroku app crashed and unable to restart
body: <p>My Rails app that uses Spree and is hosted on Heroku was working fine until last night but I woke up this morning to find that the app had crashed and I have no clue why. I have not made any changes recently. I tried heroku restart without success. It looks like something is up with Heroku (the log is asking me a question about whether the amazon host is running??) How do I let them know to resolve this for me?</p>
