bugzilla.mindrot.org having problems?

[Jacob Hoffman-Andrews]

I went to update an issue today, and I'm getting empty responses from
bugzilla.mindrot.org. In Chrome, this manifests as
"bugzilla.mindrot.org didn’t send any data. ERR_EMPTY_RESPONSE". I've
also attached a verbose curl log that demonstrates the same thing:
