That's downtime to address the brokenness, or loss of availability
>1% after you count time users waste trying to navigate large
carriers' confusing telephone IVR mazes designed to obscure access to
helpdesk, hold time,  time waiting for callbacks,  and  finally,
non-resolution of  double-NAT issue  without user paying extra for
non-NAT IP;  which is all different from network latency, and of much
greater impact than a latency increase <0.1ms.
