There's nothing like having hard data to shove in front of the noses of
connectivity providers (whether colo / cross-connect or metro dark fibre
providers) when unexplained problems suddenly start happening for no
apparent reason.  "This is what it was like before and this is what it's
like now, and this ledge here shows that the problem is on a segment that
you manage. Please explain".
