CLIENT CASE STUDY — DISASTER RECOVERY & INFRASTRUCTURE
AO IT Consulting | Portland, Oregon | aoitconsulting.com
A locked server closet. A broken air conditioner. A cause of failure nobody saw coming. And a heatsink that gave up on life at 130 degrees.

Client Engineering Company |
Cause AC Failure (Root Cause: Unusual) |
Peak Temp 130°F+ in Server Closet |
Downtime Hours — Restored Same Day |
The Setup: A Perfectly Engineered Server Room
An engineering company had done everything right. They moved their servers into a dedicated closet — locked, secure, and purpose-built. They installed air conditioning to keep temperatures in the optimal range for server hardware. The setup was clean, organized, and professionally done.
The servers hummed along happily. Temperatures were controlled. Everything was perfect.
For a while.
🔥 ACT ONE: Something Is Wrong
The Slowdown Nobody Could Explain
One day, without warning, the servers started running slow. Performance degraded gradually at first, then more significantly. Eventually systems started having real issues — the kind that stop people from getting work done.
AO IT was called in to investigate. The server closet was opened. The answer was immediately, viscerally apparent.
|
🌡️ The Closet: A Summary • Air conditioning unit: not running • Closet temperature: above 130°F • Multiple hard drives: failed • RAID controller heatsink on the primary server: no longer attached to the RAID controller |
The heatsink — the component that keeps the RAID controller from overheating — had become so hot that the thermal compound holding it in place had failed entirely. It had simply fallen off. The RAID controller had been running completely unprotected in 130-degree heat.
The investigation then turned to the air conditioning unit itself. Why had it failed? The answer was outside.
🤔 ACT TWO: The Root Cause (We Are Not Making This Up)
The Outside Unit. The Cause. We’ll Just Say It.
The outdoor condenser unit for the air conditioner was located on the exterior of the building. Upon inspection, it became clear that the unit had been repeatedly subjected to — there is no delicate way to phrase this — urine from a homeless individual who had been using the area outside the building.
The corrosive damage over time had destroyed the condenser coils. The unit had quietly failed. The closet had quietly become an oven. The servers had quietly been cooking.
|
📄 Official Root Cause Analysis Condenser unit failure due to corrosive damage from repeated exposure to urine on the exterior unit. This is, to our knowledge, the only time in 20+ years of IT support that this has been the documented cause of a server outage. |
🛠️ ACT THREE: The Recovery
Disaster Recovery Mode: Activated
With the cause identified and the scale of the damage assessed, AO IT immediately shifted into disaster recovery. The to-do list was significant:
- Identified all failed hard drives across the server environment
- Sourced and installed replacement hard drives
- Replaced the failed RAID controller — complete with a heatsink that was still attached
- Initiated full data recovery and server restoration from backup
- Brought all systems back online
- Verified data integrity across the restored environment
Despite the severity of the hardware damage — multiple failed drives, a detached heatsink, a destroyed RAID controller — the client experienced only a few hours of downtime. By the end of the same day, everything was back online and fully operational.
🛡️ ACT FOUR: Making Sure It Never Happens Again
Prevention: Two Problems, Two Solutions
Once the immediate crisis was resolved, AO IT turned to prevention. Two things needed to happen:
|
🌡️ Temperature Monitoring Installed a temperature sensor in the server closet with automated text message alerts. If the temperature rises above a safe threshold, AO IT and the client are notified immediately — before any damage occurs. |
🛡️ Physical Protection Installed a protective enclosure around the outdoor condenser unit. The specific threat that destroyed the original unit has been permanently addressed. The new unit is physically protected from the same fate. |
|
“They figured out what happened, fixed everything the same day, and then made sure it could never happen again. I still can’t believe that’s what caused it. But I’m glad they found it.” — Principal, Engineering Company |
By the Numbers
|
130°F+ Temperature inside the server closet when AO IT arrived |
1 Heatsink found on the floor of the server closet, no longer on the RAID controller |
Same Day All systems restored and fully operational despite major hardware failures |
0 Temperature-related incidents since monitoring and protection were installed |
|
💡 The Lesson (Beyond the Obvious One) Yes, protecting your outdoor AC unit is now on the list. But the bigger lesson is this: server rooms fail in ways nobody anticipates. Heat is one of the most destructive forces in an IT environment, and temperature monitoring is one of the cheapest and most effective safeguards available. A $50 temperature sensor with text alerts would have caught this the day the AC started struggling — before a single drive failed. If your server room doesn’t have one, it should. |
Does Your Server Room Have Temperature Monitoring?
If the answer is no — or “I’m not sure” — let’s fix that. AO IT Consulting can assess your server environment, install temperature and environmental monitoring, and make sure the next unexpected event sends you a text message instead of a repair bill. Contact us for a free server room assessment.
