  • Services with demonstrably high usage levels
Extended business hours (7:00 am-9:00 pm), 7 days a week

Requires continuous availability, though short service outages are not catastrophic. Availability is required for effective business operation

  • Moderate impact on teaching and research
  • Moderate to significant damage to Harvard's reputation in the eyes of the Harvard community and/or general public
  • Availability is required for robust research activities
Extended business hours (7:00 am-9:00 pm), Weekdays (excluding holidays)

Continuous availability ideal, though short service outages are tolerated. Contributes to efficient business operations.
