Ask HN: Recent Experience with Heroku

Over the past weekend I moved my blog off of Tumblr to Heroku. Their documentation couldn't have been more clear and deployment was dead simple. However, day 2 after my launch I find if I hit the site (as of 5:45am EST) I get an application error. I'm finding the same for heroku.com as well, although status.heroku.com shows no problems.

So I'm asking for other's experience with reliability and support at Heroku. I'm in the process of building something and I'd rather not launch on an unstable platform.
