• Even if the server and database are "up", the system as a whole isn't entirely "available" within the context of every process or case usage. I mean, you can have a technically successful fail-over and still not have all the storage mappings, logins, and OS dependencies in place and working. Some users will say it's available and some will say not. Likewise, unacceptable latency can exist for specific processes and users even when the server overall is running in top form.
