What's the difference? I'm talking about HTTP 304, not HTTP 404.

You are absolutely correct but I claim a two-week outage of the
aggregates served from md.incommon.org has probability zero. In any
case, you asked what would happen and I told you (although now that I
think of it, you already knew what I said so you must have been asking
something else).

are like apples and oranges.
