* Past and Current System Availability Statistics *


Availability percentages are calculated using gross wall clock time.Outages/periods of unavailability (downtime) are subtracted from the total wall clock hours and presented as the percentage of the time the system was available to the users. The downtimes are scheduled and unscheduled periods of non-availability grouped into the following three categories: Hardware (H/W), Software (S/W), and Other (Oth). The Oth category includes unavailable time caused by power outages, environmental conditions and planned power-downs for equipment relocations or computer room modifications, security related conditions, etc.

To view a summary of number of downtimes and cumulative hours, go to theOverall Systems Availability Details.
