TL;DR
A blogger migrated a decade-old website from Ubuntu 16.04 to FreeBSD, citing security and performance benefits. The move involved using FreeBSD Jails and ZFS on a Hetzner VPS, marking a significant platform upgrade.
A blogger has migrated their website from Ubuntu 16.04, which had been running for over ten years, to FreeBSD on a new Hetzner virtual machine, citing security improvements and technical experimentation as key reasons.
The blog was hosted on a Digital Ocean VPS with Ubuntu 16.04, which reached end-of-life support, raising security concerns. The migration involved moving to a Hetzner VPS costing less than €6 per month, offering better hardware specs and performance. The switch included adopting FreeBSD, specifically leveraging Jails for containerization and ZFS for filesystem management, to enhance security and flexibility.
The original setup was serving static content via nginx, with outdated software and a long uptime of approximately four years. The new environment aims to isolate each site within separate FreeBSD Jails, allowing easier management and improved security. The migration also served as a technical challenge and exploration into FreeBSD’s capabilities, particularly its Jails and ZFS features.
Why It Matters
This move highlights the importance of maintaining up-to-date and secure server environments, especially for long-running websites. It demonstrates how alternative operating systems like FreeBSD can offer advantages in stability, security, and cost-efficiency. For other site owners, this case underscores the potential benefits of adopting FreeBSD and containerization techniques, especially as Linux distributions age out of support.

Background
Ubuntu 16.04, released in April 2016, reached end-of-life support in April 2021, meaning it no longer received security updates or package repository maintenance. Many users running outdated Linux distributions face increasing security risks. The blogger’s previous setup was simple, serving static sites with a long uptime, but the end of support prompted a reassessment. FreeBSD, known for its stability and security features, especially Jails and ZFS, has been gaining interest among experienced system administrators. The migration also reflects broader industry trends toward containerization and filesystem resilience.
“Moving from Ubuntu 16.04 to FreeBSD was both a technical challenge and a step toward better security and performance.”
— the blogger
“FreeBSD Jails provide a lightweight, secure way to isolate services, similar to containers but with a different philosophy.”
— system administrator

Key Questions
Why did the blogger choose FreeBSD over other operating systems?
The blogger was interested in FreeBSD for its reputation for stability, security, and advanced features like Jails and ZFS, which offer better isolation and filesystem management compared to traditional Linux setups.
What are FreeBSD Jails, and how do they compare to Docker containers?
FreeBSD Jails are a form of lightweight virtualization that sandbox applications within isolated environments sharing the same kernel, similar to Docker but with a different design philosophy emphasizing system-level separation.
What benefits does ZFS provide in this setup?
ZFS offers features like data integrity, snapshots, and easy management, allowing the blogger to create reliable backups and recoveries without relying solely on VPS provider snapshots.
Will the migration impact website performance or uptime?
The blogger reports that the new setup is performing well, with better hardware specs and optimized configurations, but long-term performance data is still being collected.
Are there security risks in running outdated Linux distributions like Ubuntu 16.04?
Yes, once support ends, no further security updates are provided, increasing vulnerability to exploits and attacks. Upgrading or migrating to supported systems is recommended for security.
