We changed the title from "Heroku is Down" (originally, "Heroku has been down for more than 1 hour") in an attempt to make it more accurate. Happy to change it further if anyone suggests a better title.

In general, "Foo is Down" doesn't make for very good HN posts, because while it matters to users of Foo, the fact that Foo is down usually isn't intellectually interesting (which is what HN is looking for in a submission). Postmortems about why Foo went down, on the other hand, are often fascinating. Conclusion: we should usually wait for the postmortem.
