Comment 3 for bug 631262

I believe it depends on what delivered the message he reported ("Couldn't connect to Launchpad, please wait and try again"). In my experience, if the browser delivered the message, that would be something like bug 640065. If Apache delivered the message, that would be a different cause.

That said, I can imagine Apache doing something that would surprise my simple categorization above. I'll leave it as a dupe unless there's actually indication of a different cause.
