This article provides a comprehensive overview of the maintenance, its potential impact, and how users can stay informed. This SecOps News is important for users who are using Cloudflare services.

Scheduled Maintenance Details
Cloudflare ICN (Seoul) data center is undergoing scheduled maintenance on December 1, 2025, from 17:00 to 21:00 UTC. During this four-hour window, Cloudflare will be performing necessary upgrades and maintenance tasks to ensure the continued reliability and performance of its services. This routine maintenance is essential for maintaining the integrity and efficiency of Cloudflare's global network.
The primary goal of this maintenance is to enhance the infrastructure and ensure optimal performance. Cloudflare's proactive approach to maintenance helps prevent potential issues and ensures a seamless experience for its users. By scheduling maintenance in advance, Cloudflare aims to minimize disruption and provide users with ample time to prepare.
The maintenance window is strategically chosen to minimize impact on users. Cloudflare carefully considers traffic patterns and peak usage times when scheduling maintenance. This proactive approach helps reduce the likelihood of significant disruptions and ensures that the majority of users experience minimal inconvenience. Cloudflare's commitment to transparency and proactive communication ensures that users are well-informed about any potential service impacts.
Potential Impact on Users
During the maintenance window, there is a possibility of a slight increase in latency for end-users in the affected region. This is because traffic might be re-routed from the ICN (Seoul) data center to other locations within Cloudflare's global network. While Cloudflare's network is designed to handle such re-routing seamlessly, a temporary increase in latency is a potential side effect.
For PNI / CNI customers connecting with Cloudflare in Seoul, it is crucial to ensure that their systems are prepared for traffic failover. Network interfaces in the ICN data center may become temporarily unavailable during the maintenance window. This means that traffic destined for Seoul should be automatically re-routed to alternative locations to maintain connectivity and service availability.
Cloudflare's global network is designed with redundancy and failover capabilities in mind. This ensures that services remain available even during maintenance or unexpected disruptions. By distributing traffic across multiple data centers, Cloudflare minimizes the impact of any single point of failure. This robust infrastructure is a key component of Cloudflare's commitment to providing reliable and resilient services.
How to Stay Informed
Cloudflare provides several channels for users to stay informed about scheduled maintenance and other service updates. Subscribing to notifications via the Cloudflare dashboard is the most direct way to receive timely updates. Users can choose to receive notifications via email, PagerDuty, and webhooks, depending on their plan and preferences.
The Cloudflare Status Page is another valuable resource for real-time information about the status of Cloudflare's services. This page provides updates on incidents, maintenance, and overall system performance. Users can check the status page at any time to get the latest information about Cloudflare's network and services.
Cloudflare's commitment to transparency is evident in its proactive communication practices. By providing multiple channels for users to stay informed, Cloudflare ensures that users have access to the information they need to manage their services effectively. This transparency builds trust and reinforces Cloudflare's dedication to customer satisfaction.
Preparing for the Maintenance
To minimize any potential impact from the maintenance, users should ensure their systems are configured to handle traffic re-routing. This is particularly important for PNI / CNI customers connecting with Cloudflare in Seoul. Verifying that traffic can fail over to alternative locations will help maintain service availability during the maintenance window.
Reviewing Cloudflare's documentation on traffic management and failover is also recommended. Cloudflare provides comprehensive resources to help users understand how to configure their systems for optimal performance and resilience. These resources can be invaluable in preparing for scheduled maintenance and other potential disruptions.
Proactive planning is key to minimizing the impact of any maintenance event. By taking the time to review configurations and ensure failover mechanisms are in place, users can ensure a seamless experience even during maintenance windows.
