Yes, but not signing isn't "the aggregate's not available". I thought that's 
what was meant by an outage in this discussion.

I think a 2 week outage of the aggregate would be noticed, and would be 
catastrophic. I'm not seeing a huge difference there...

Again, I'm sort of just playing devil's advocate here. I get the point you 
and Walter and Nick are making. I'm just trying to say that the aggregate's 
availability isn't meaningless either.

I do believe, however, that solving the problem by making every deployer 
operate a caching MDQ proxy is not an answer. If the consensus of the group 
is that the endpoint software needs to do more here, I can take that to 
heart, but looking at the problem from a broader perspective, I think that 
road leads to the conclusion that endpoints need to host the metadata.
