Agreed.  Rare that people do haircuts on router configs; they're
tedious and can not be delegated to an intern or someone else who
doesn't have historical context.  I just cut a config by half by
removing unused ACLs, and even that is fairly painful.

It's been almost nine and a half years and was a short-lived problem,
but I'll betcha that an announcement from AS 7007 will have
reachability problems to a measurable fraction of the Internet.  That
would make a kind of cool experiment.  Vinny, you listening?
