One-Year Raspberry Pi Colocation Experience Report
I completed a twelve-month production deployment using Raspberry Pi 4B units (4GB RAM, 1.5GHz quad-core ARM Cortex-A72) housed at a regional colocation facility. Key findings:
- Power consumption: 7.5W sustained per unit
- Uptime: 99.2% annual average
- Thermal throttling events: 847 during July-August 2025
- Migration trigger: CPU frequency reduction to 600MHz during sustained 35C ambient
The thermal performance deficit made continued operation non-viable for production workloads. All services migrated to KnownHost standard VPS instances effective August 15, 2026.
