Quick Review of The Google Cloud Outage (2025.03.29）
Google Cloud experienced a significant outage in its US-east5-c zone in Ohio on March 29, 2025. The disruption lasted approximately six hours and affected over 20 services, including BigQuery, Cloud VPN, Cloud SQL, and Virtual Private Cloud.
The root cause was traced to a failure in the uninterruptible power supply (UPS) systems. Specifically, a voltage swell event caused a mismatch between the voltage tolerances of the UPS and the connected network equipment. The UPS was designed to tolerate up to 120% of the nominal voltage, while the network equipment could handle up to 110%. When the swell exceeded this, the network equipment entered protective shutdowns.
What made the situation more critical was that the voltage swell persisted for nearly a minute—long enough to trigger cascading failures. In response, Google Cloud had to manually reboot services and reallocate resources to stabilize operations, which highlights the need for tighter UPS power backup configurations, voltage harmonization, and real-time monitoring in cloud data centres.
Reflection and Insights from The Incident
This incident underscores the critical importance of robust UPS power backup systems in maintaining cloud service reliability. The failure highlighted the need for precise alignment between UPS configurations and the tolerances of connected equipment.
In response, Google implemented several remediation measures, including reconfiguring the datacenter-level UPS voltage regulator and deploying a double conversion UPS in the affected datacenter's power distribution design. These steps aim to enhance resilience against future voltage fluctuations and ensure that UPS systems can effectively provide backup power during outages.
What is The Core Value of an Uninterruptible Power Supply?
An uninterruptible power supply (UPS) is a device that provides emergency power to connected equipment when the main power source fails. It acts as a buffer, preventing disruptions during blackouts, surges, or voltage drops. Its core value lies in preserving uptime, data integrity, and operational continuity, which make it essential for today’s power-reliant world.
The Function of A UPS
1. Enterprise-level: At the enterprise level, a UPS is essential for data centres, hospitals, financial institutions, and industrial facilities. It protects servers and critical infrastructure from downtime and data loss during power disruptions. A robust, uninterruptible power supply ensures uninterrupted workflow, prevents costly outages, and supports smooth switchover to backup generators.
2. Personal level: For home offices or individuals, a UPS safeguards computers, routers, and entertainment systems. It allows users to save work, safely shut down devices, and maintain internet connectivity during brief outages. As remote work becomes more common, personal-level uninterruptible power supplies are gaining popularity for added reliability.
The Limitations of Traditional UPS
While traditional UPS systems are invaluable, they come with notable limitations, such as:
§ They often rely on lead-acid batteries, which require regular inspections and timely replacement.
§ Maintenance is easy to neglect, especially in non-IT environments. This may lead to degraded performance or complete failure when backup is most needed.
§ Traditional UPS models can also be bulky, less energy-efficient, and are not ideal for solar or renewable power integration.
§ Older UPS units can produce significant heat, requiring dedicated cooling systems to prevent overheating.
§ Most traditional UPS systems emit noticeable noise during operation. This will cause disruption in quiet environments like home offices or bedrooms.
These limitations highlight the growing need for modern, easy-to-maintain UPS solutions that offer better performance, longer life cycles, and compatibility with clean energy systems.
Daily "Electricity Anxiety" Scenarios and Needs
In our tech-driven world, sudden power outages can trigger what many call “electricity anxiety.” The term refers to the fear of losing power-dependent conveniences or essentials.
