When a major typhoon threatens, organizations focus heavily on physical building security—boarding windows, clearing drains, and securing outdoor assets. However, for modern businesses, IT infrastructure is often the most vulnerable and critical asset. A prolonged network outage, flooded server room, or corrupted database can cripple operations long after the storm has passed.
A comprehensive guide outlines how to safeguard your organization's IT infrastructure before, during, and after a typhoon.
1. Pre-Storm Preparation: Hardening Your Systems
Preparation begins long before a storm warning is issued. When a typhoon is tracking toward your region, proactive measures must be executed methodically.
Data Protection and Backups
Verify the 3-2-1 Rule: Ensure you have at least three copies of your data, across two different media types, with at least one copy stored off-site or in the cloud.
Perform Full Backups: Run comprehensive backups of all critical databases, virtual machines, and user files immediately before the storm hits. Test the restoration process to guarantee data integrity.
Secure Cloud Replicas: If your primary data center is in the typhoon’s path, ensure that your cloud replication services (e.g., AWS, Azure, Google Cloud) are synced and active in a safe, non-impacted geographic region.
Data Center & Server Room Physical Safety
Elevate Critical Assets: If your server room or communication closet is prone to ground-level flooding or heavy seepage, move critical hardware, switches, and backup servers to higher racks or upper floors.
Mitigate Water Risks: Seal cable entries against driving rain. Move equipment away from exterior walls and windows. Cover server racks with heavy-duty waterproof plastic sheeting as a last line of defense against roof leaks.
Power Conditioning and UPS: Test your Uninterruptible Power Supply (UPS) units. A UPS bridges the gap during sudden grid fluctuations and gives systems enough clean power to initiate safe, automated shutdowns.
Generator Readiness: Test emergency backup generators, check fuel levels, and ensure you have a secured contract for fuel replenishment if commercial supply chains are disrupted for days.
2. During the Typhoon: Monitoring and Continuity
Once the storm makes landfall, human intervention on-site becomes dangerous or impossible. Your infrastructure must rely on automated fail-safes and remote management.
Remote Monitoring & Alerting: Utilize out-of-band management (OOBM) and cellular-backed network connections to keep an eye on environmental sensors (temperature, humidity, water leaks) and server health remotely.
Execute Failover Protocols: If local power fails and generators kick in, monitor fuel consumption and load distribution. If a data center site loses primary grid power and generator failure is imminent, trigger graceful shutdowns for non-essential workloads to preserve runtime for core services.
Maintain Communication Channels: Keep IT response teams connected via redundant communication platforms (e.g., satellite phones or cellular groups with external battery banks) to manage incident response dynamically.
3. Post-Storm Recovery: Safe Restoration
After the eye of the storm passes and local authorities give the "all clear," rushing back to turn everything on can cause catastrophic electrical short circuits or hardware damage.
Inspect Before Powering On:
Check the facility for structural water damage, roof leaks, or standing water near electrical panels and server racks.
Do not touch or boot up any equipment that has come into contact with floodwaters until it has been professionally cleaned, dried, and tested.
Grid Stability Check: Utility power coming back online is often unstable, characterized by heavy voltage spikes and surges. Allow the commercial power grid to stabilize for a few hours before switching off backup generators and reconnecting sensitive infrastructure.
System Integrity Checks:
Bring systems online in a tiered sequence: core networking infrastructure first, followed by storage and hypervisors, and finally domain controllers, databases, and user-facing applications.
Run diagnostic scripts to check for data corruption or hardware degradation caused by humidity and thermal spikes.
Post-Incident Review: Conduct a debrief with your IT and disaster recovery teams. Document what worked, identify bottlenecks, and update your runbooks to ensure even greater resilience for the next storm season.
