Hong Kong Data Center Maintenance
Essential Hardware Upgrades for HK4
Friday, April 3, 2026 – Scheduled Power Cycling for Performance & Reliability
Maintenance Window: 16:00 to 23:59 (HKT/GMT+8) | 08:00 to 16:00 (UTC)
Why Are We Performing This Maintenance?
In the fast-paced landscape of Hong Kong hosting, staying still means falling behind. The HK4 facility is a strategic hub for UnderHost, providing low-latency connectivity to mainland China, Southeast Asia, and global markets. To maintain our commitment to offshore hosting and high-performance computing, we must periodically upgrade our core infrastructure.
This specific maintenance involves critical network switch firmware updates and power distribution unit (PDU) enhancements. These upgrades are essential to prevent the common issues faced in Hong Kong data centers, such as network bottlenecks and hardware failures that lead to unexpected downtime. By proactively replacing and upgrading these components, we are adhering to the best practices of hardware lifecycle management, ensuring that your VPS and dedicated servers run on the most reliable equipment available [citation:7].
Impacted Services: What You Need to Know
During the maintenance window on Friday, April 3, 2026, from 16:00 to 23:59 Hong Kong time, all physical and virtual services located in our Hong Kong facility will be temporarily powered off. This includes:
- All VPS (Virtual Private Servers) hosted in HK
- All Dedicated Servers housed in HK
This hard shutdown is necessary because the upgrades are at the electrical and physical networking layer. Simply rebooting the virtual layer is insufficient; we need to ensure the power supply stability and core switching fabric are 100% optimized to prevent issues like packet loss or voltage irregularities post-upgrade. Once the maintenance is completed, all systems will be powered back on automatically.
Unsure if your service is in HK? Log into your client area at @CustomerPanel and check your service details, or simply open a support ticket and we’ll confirm it for you instantly.
Our Commitment: Transparency & Proactive Support
We understand that an 8-hour maintenance window raises questions. To be fully transparent, we are following industry-standard protocols seen with global providers who regularly schedule maintenance in their Hong Kong PoPs to ensure stability.
Step 1: Backup
- Run a full backup via your control panel.
- Consider offsite backup solutions.
- Verify backup integrity before the 3rd.
Step 2: Schedule
- Plan your cron jobs around the window.
- Notify your users of potential downtime.
- Update your DNS TTLs if you have a failover.
Step 3: Confirm
- Unsure? @CustomerPanel to verify location.
- Need temp VPS? Request now.
- Bookmark our live status page.
The Long-Term Benefit: Why “Planned” Beats “Unplanned”
In the world of Hong Kong servers, unplanned downtime is the real enemy. Studies show that a significant percentage of Hong Kong VPS failures stem from maintenance neglect rather than hardware age. By scheduling this maintenance, we are addressing the root causes of instability before they affect you.
Post-maintenance, HK will feature enhanced power redundancy and cooling system efficiency, which is vital given Hong Kong’s subtropical climate and the high-density demands of modern servers. This directly translates to a lower probability of thermal throttling or power surges disrupting your business. We are investing in the green and sustainable operation of our data center to ensure it meets the highest international standards for management and maintenance.
Need a Temporary Home for Your Workloads?
We value your business continuity. If an 8-hour window is critical for your operations, we can spin up a temporary VPS for you in another region (like Moldova or the Netherlands) at no additional cost for the rental during the migration period.
