In late January 2026, several nodes in CloudCone’s US Los Angeles DC02 data center experienced a severe incident. A large number of VPS instances suffered disk corruption, data encryption, or complete data deletion. Subsequent official investigation confirmed that a security misconfiguration in the Virtualizor control panel was exploited, allowing attackers to gain root access to the host machines, triggering a chain reaction across multiple servers.
The impact was widespread. Some users who had not implemented offsite backups lost their data permanently. Only a small portion of instances were restored via reboot, while the majority required full system reinstallation. After more than ten days of recovery efforts, CloudCone gradually restored services and announced its compensation plan between February 10–12.

This article is based on official announcements and publicly available community information. It provides an objective review of the incident and further analyzes the risks of unmanaged VPS usage and the importance of backups.
1. Brief Timeline of the Incident
- Time: Late January 2026
- Location: CloudCone Los Angeles DC02 Data Center
- Symptoms: VPS disk corruption, data encryption, or deletion
- Cause: Weak security configuration in the Virtualizor control panel, exploited via a vulnerability that granted root access to the host server
- Impact: Many VPS instances required reinstallation; only a few recovered after reboot
Virtualizor has previously been involved in similar security incidents across the industry. Some hosting providers (such as OuiHeberg, ColoCrossing, etc.) have also been affected by comparable attacks. This incident once again highlights the critical importance of securing virtualization control panels.
2. CloudCone Official Compensation Summary

3. Community Sentiment and User Feedback Overview
Across X (Twitter), LowEndTalk, Nodeseek, Zhihu, and other communities, user feedback is generally divided into two main perspectives:
1) Views on the Compensation Plan
- Some users believe the “renewal-triggered compensation” model encourages continued usage of the service
- Some users argue that data value cannot be fully compensated by service time or credits
- Others feel that having a clear compensation plan is still better than none
Overall, users remain more concerned about data recovery and security assurance rather than monetary compensation alone.
4. Technical and Industry Insights Behind the Incident
1) Virtualizor Control Panel Security Risks
Virtualizor operates with high privileges on host machines. Once a remote code execution (RCE) vulnerability exists, attackers may gain full control of the physical server, impacting all VPS instances running on it.
For small and mid-sized hosting providers:
- Limited security hardening capabilities
- Delayed patch updates
- Weak risk mitigation frameworks
Such control panel vulnerabilities tend to have a cascading impact once exploited.
2) Positioning of Low-Cost Unmanaged VPS
Most low-cost VPS offerings are unmanaged services, characterized by:
- Low price
- No system-level maintenance support
- No responsibility for user data protection
- Only uptime guarantees in most cases
These products are more suitable for:
- Testing purposes
- Personal learning environments
- Non-critical project deployment
For production use, users must take full responsibility for backups and disaster recovery.
3) Importance of Backup Strategies
Once data is lost, recovery is often impossible. Recommended strategies include:
- Offsite backups (different data centers)
- Multi-platform storage
- Regular automated backups
Common backup solutions include:
- Cloudflare R2 (10GB free tier)
- Backblaze B2 (10GB free tier)
- Alibaba Cloud OSS
- Tencent Cloud COS
The cost of backups is far lower than the risk of data loss.
5. Frequently Asked Questions (FAQ)
Q1: Does CloudCone offer cash compensation?
Official compensation is provided in the form of account credit, service extension, and backup service discounts. No direct cash refund has been announced.
Q2: Is data recovery possible?
According to public information, most unbacked-up data is unrecoverable. Only a small number of instances were restored via reboot.
Q3: Should users continue using CloudCone?
It depends on use cases. For testing or non-critical workloads, users may wait for the new platform stability. For production workloads, providers with stronger SLA guarantees and backup systems are recommended.
Q4: Are low-cost VPS inherently unsafe?
Not necessarily, but generally:
- Lower service guarantees
- Compensation mainly in service credits
- User is responsible for data security
Proper usage scenarios and backups are key.
6. Rational Conclusion
This CloudCone DC02 incident highlights the importance of control panel security and host privilege management. It also reinforces several key points:
- Unmanaged VPS is inherently a “self-managed risk” product
- Providers primarily guarantee uptime, not data safety
- Backups are always the top priority
For users of low-cost VPS services, price advantage should never be mistaken for risk-free reliability. Proper backup planning and disaster recovery strategies are essential for long-term stability.
