--- title: "Infrastructure: eight servers, five providers, four countries" description: "Eight servers at Hetzner, UpCloud, Infomaniak, Scaleway and Tavuru in Switzerland, Germany, the Netherlands and France, with three copies of every database." url: https://elchi.dev/en/infrastruktur language: en --- Infrastructure # The sky above our servers. Everything we offer runs on a cluster of eight servers of our own, since 3 October 2026. Over every city with a server, a bright star stood almost exactly at the zenith at midnight that night. Joined like the servers are joined, they make the mark of Elchi Studios. Midnight, 3 October 2026, Swiss time. Five stars in Andromeda, Paris in Lacerta, each 0.2 to 1.0 degrees from the zenith of its city. Point at a star to see its servers. Stereographic projection, east to the left. Stars to magnitude 6.5 from the Bright Star Catalogue (Hoffleit and Warren, CDS V/50). servers 8 server providers 5 countries with servers 4 copies of every database 3 Cluster inventory, as of 8 October 2026.

When one fails, the other takes over. - **Application**Run the applications, both at once. - **Database**Every change lands on all three. When the first fails, another takes over. - **Watcher**Checks the others from outside, around the clock. ## How the cluster works ### No third-party proxy in front A request is encrypted from the browser to our own entrance, and from there onward over our own encrypted network between every server. No third party sits in between and reads along. ### Two of everything Two entrances at two providers, two application servers in two countries, three databases in three data centres. No provider holds both halves of a pair. ### Measured and published status.elchi.dev shows what is running and every incident at its real length. The measured availability appears once a full month has been measured; the cluster has run since 3 October 2026. ### Names and certificates The DNS zones are held by Cloudflare, and ClouDNS answers lookups with the healthy entrances. Both see only names, no content and no accounts. [To the status page](https://status.elchi.dev/) [Who sees which data](https://elchi.dev/en/vertrauen)
