At Down To Zero (DTZ) we believe a modern cloud platform can — and should — be both estremamente affidabile che delicata con il pianeta.
Our answer is a twin-site architecture that pairs a private, solar-powered micro-datacenter in Leipzig with a fully redundant footprint inside Hetzner’s flagship facility in Falkenstein. Together they give us three things every customer cares about:
Below we dig into the what, why, and how.
La Germania si trova all’incrocio della dorsale Internet europea, offrendo tempi di andata e ritorno inferiori ai 30 ms verso la maggior parte delle capitali UE e collegamenti diretti ai principali Internet Exchange Point (IXP) di Francoforte (DE-CIX) e Berlino. Regolamentazioni ambientali e sulla privacy rigorose (pensate alla Energieeffizienzstrategie e al GDPR) sono inoltre in linea con i nostri valori:
| Responsibility | Leipzig | Falkenstein (Hetzner) |
|---|---|---|
| Workload type | Asynchronous / batch | Synchronous / latency-critical |
| Power source | On-site PV array | 100 % renewable grid contracts |
| Operating mode | Eco-mode (compute only when sun shines) | 24 × 7 always-on |
| PUE* snapshot | n/a | 1.18 (Hetzner public report) |
*PUE = Power Usage Effectiveness, più basso è meglio.
Our Leipzig cluster is literally fueled by daylight:
Typical tasks here include CI/CD pipelines, nightly ETL, large-scale rebuilds, and generative-AI batch inference — anything that tolerates a flexible runtime window.
For real-time APIs, ingress proxies, we anchor in Hetzner’s facility:
We also spin up overflow async pods here when Leipzig’s sky goes grey — maintaining job SLA without compromising eco-goals.
Two locations, one mission: deliver production-grade cloud services while driving operational carbon to zero.
If you’re looking for a platform that puts sustainability on equal footing with speed and uptime, we’d love to hear from you.
