Also, the possibility of equipment failure should *always* be factored into backout/recovery plans. You can have all the faith in your hardware that you want, but Murphy has enable/root. If it's something has simple as having redundant capacity to shift the load to, or as drastic as having a spare chassis sitting on hand, it's always a possibility, however remote. - billn On Mon, 28 Mar 2005, Matthew Kaufman wrote: My opinion: For the customer, the outage starts when their service stops working* and ends when their service starts working again. Your goal should be to make that all happen during the maintenance window. If it doesn't, then the part that was during the window is "planned outage" and the part that wasn't is "unplanned outage". Good ISPs have good explanations for, and sometimes even monetary credit, for "unplanned outages". "Planned outages" can simply be explained by pointing at the announced maintenance interval policy.

Some customers are unhappy if their traffic is taking the slightly longer alternate path, others are happy as long as they can reach CNN, even if the rest of the net disappears.
