-----------
Addressing outages (downtime) hasn't changed much. Nothing is new under the sun. As a network engineer you know the answer I'm going to give, it depends who you ask and what SLA customers agree on. As Joseph alluded to, you get what you pay for. Sometimes even that proves us engineers wrong due to bad design.

All I'm saying is keep your customers posted that goes a long way as opposed to having them play "hunt the secret glyph".
