Server Room Resilience Checklist

Print, save or use this list during operational reviews.

Confirm room temperature is within the approved operating range and review recent trend or alarm history
Check cooling units, airflow paths, filters, drainage and any known maintenance condition that could reduce effective cooling
Verify the complete protected power path from utility or distribution through UPS, batteries, bypass and rack power distribution
Review current UPS alarms, battery condition, load level and the documented response for utility or UPS failure
Confirm racks have clear front-to-back airflow, safe cable routing, no blocked vents and no unmanaged heat sources
Verify environmental monitoring is active for temperature and any other approved room conditions, with a named alert recipient and escalation path
Confirm physical access is restricted, emergency access is defined and the room is free from unnecessary storage or obstruction
Check that critical devices, power circuits, UPS feeds, network links and service ownership are documented well enough for another engineer to understand the room
Review backup connectivity or service-continuity dependencies that could fail together with the room, including carrier, network and management paths
Confirm maintenance contacts, vendor support paths and escalation authority are current without storing credentials in the checklist
Record open risks, temporary workarounds, responsible owner and target action date
Recheck the room after significant electrical, cooling, rack, network or infrastructure changes
