I've encountered this problem twice this year. In February, for three weeks, the inlet air temperature suddenly rose to 35C, which took a week of emails and communication to resolve.
Finally, it returned to its normal temperature of 22C. But now, after two weeks, it has risen again to 33C. Either the A/C in the server room is turned off or malfunctioning, or my server is receiving hot air from another device. Is anyone else in the LA location facing the same problem?

When we were a customer there, we faced some problems in the past. The router temperatures were extremely high, and I think they only placed a large fan in front of our rack to resolve the issue. In my opinion, the building is not suitable for a data center.

Although the company was generally good, we had to switch to another provider after experiencing several outages. You may want to consider their new data center, which could be better since it's located in a newer building.

Typically, colocation providers will only guarantee the air temperature in the cold aisle of the data center. Inside the cabinets is the customer's responsibility, which can become complicated, especially when using shared cabinets. If the temperature inside the cabinet is too high while the rest of the facility is well-maintained, it usually means one of several things:

1. The cabinet setup is not properly organized, with gear blocking the airflow in the rear, or incorrect installation by customers, allowing hot air to escape into the cold aisle.
2. The physical design of the cabinet is problematic, such as running servers inside cabinets with plexiglass or solid rear doors when there are limited chimney exhaust systems.
3. The cabinet's electrical capacity is oversold, with more power sold to a cabinet without considering the limitations of airflow through the door perforations.
4. Lack of proper airflow management inside the cabinet, such as strip brushes to stop in-cabinet recirculation, and blanking panels in open rack units.
5. Someone is obstructing the cabinet's airflow, by placing objects in front of or behind the cabinet.

Based on the information provided, it seems like this is a shared cabinet, and not enough effort is being put into monitoring what's happening inside it. The best way to confirm this is to visit the site directly during an event or request pictures or video call.

The temperature fluctuations you've experienced, from the sudden rise to 35°C followed by the return to 22°C and the recent spike to 33°C, are certainly concerning and require a thorough investigation.

Let me delve into the potential causes and the steps I would recommend to address this issue:

1. Assess the Air Conditioning (A/C) System:
  - Conduct a comprehensive inspection of the A/C unit serving the server room. Verify that it is functioning correctly, with the appropriate refrigerant levels, clean filters, and proper airflow.
  - Check the thermostat settings and ensure that the A/C is set to maintain the desired temperature range, typically between 20-25°C for server rooms.
  - Evaluate the A/C unit's capacity and ensure that it is adequately sized to handle the cooling load of the server equipment and the overall server room environment.
  - If the A/C unit appears to be malfunctioning or undersized, coordinate with the HVAC team or a qualified technician to repair, replace, or upgrade the system as necessary.

2. Analyze the Airflow and Cooling Dynamics:
  - Conduct an airflow assessment within the server room to identify any potential hot spots or areas of recirculation.
  - Examine the server rack arrangement, cable management, and the positioning of equipment to ensure optimal airflow and efficient heat dissipation.
  - Consider implementing airflow optimization techniques, such as using server rack baffles, blanking panels, or hot/cold aisle containment, to improve the overall cooling efficiency.
  - Investigate the possibility of hot air being introduced from adjacent areas or other devices within the server room, and take measures to isolate and contain the airflow.

3. Enhance Environmental Monitoring:
  - Install additional temperature and humidity sensors throughout the server room to gain a more comprehensive understanding of the thermal profiles and identify any localized hot spots.
  - Integrate the sensor data into a centralized monitoring system that can provide real-time alerts and historical trends for temperature and humidity levels.
  - Establish thresholds and alarm triggers to promptly notify your team of any significant deviations from the optimal operating conditions.

4. Coordinate with Facilities and Other Teams:
  - Engage with the facilities management team to understand if there are any broader HVAC system changes or issues within the building that could be impacting the server room's temperature.
  - Collaborate with other departments, such as IT operations, to rule out any server-specific issues or changes that may be contributing to the temperature fluctuations.
  - Establish clear communication channels and escalation procedures to ensure a coordinated response when addressing temperature-related incidents.

5. Develop a Comprehensive Incident Response Plan:
  - Create a detailed incident response plan that outlines the steps to be taken when temperature-related issues arise, including the roles and responsibilities of your team members.
  - Ensure that the plan includes contingency measures, such as temporary cooling solutions or the ability to safely shut down and relocate servers if the temperature exceeds critical thresholds.
  - Schedule regular drills and training sessions to ensure your team is well-prepared to respond effectively to temperature-related incidents.
