Filecoin infrastructure,
run by operators.
Daily mainnet snapshots, calibration faucet, archival history. Served from a Tier-grade datacenter on Norwegian hydroelectric power, with a 20 Gbit direct uplink and no CDN middleman.

Networks and operators we've shipped with
What we run
Three services. One operator. One datacenter.
The boring kind of infrastructure that just works. Generated, replicated and served on hardware we own, in a building we know.
Mainnet snapshots
Daily mainnet .car.zst, Lotus and Forest compatible, resumable downloads over HTTP Range.
Calibration faucet
tFIL and USDFC from a single dispenser, public API with key-based auth for CI and CLIs.
Archive snapshots
Historical lite-archival snapshots at ~30k-epoch intervals, back to early 2026.
Operator-grade by default
Built for the people running nodes at 3 AM.
Stax is operated by long-running Filecoin engineers, not a hyperscaler reselling someone else's pipeline. We read the source code of the things we serve, and we run the same software on our own boxes.
- Direct uplink, no CDN tax
- 20 Gbit straight to our serving node. Large .car.zst files don't cache well on free CDN tiers, so we don't pretend they do. Downloads go to the wire.
- Sole-vendor risk, eliminated
- Until now there has effectively been a single production source for Forest-format snapshots. We give the network a second, independent one, with the same file format and a drop-in import path.
- Resumable, range-aware
- HTTP 206 Partial Content tested in production. Drop a connection, resume from byte n. Built for ops who don't want to babysit a wget.

stax_snapshot_mainnet_2026-06-04_height_6075840.car.zst: OKWhere it runs
A Norwegian datacenter, by a Norwegian river.
Stax Infra runs out of BB110 in Drammen — a purpose-built facility with energy rating A, sat where the Drammenselva river meets the fjord. Hydro upstream, fiber downstream, fjord cold for free, and clean cold mountain air all winter.
Bjørnstjerne Bjørnsons gate 110 · 3044 Drammen · Q1 2018 build · Energy rating A
BB110 · Bangeløkka, Drammen
Hydroelectric
Norway runs ~98% on renewables. The grid feeding the facility is dominated by hydro from the same mountain watershed that built the country.
Cooled by climate
Drammen averages 7 °C annually. Free-air cooling is the baseline, not the exception. PUE stays close to 1.0 most of the year.
Fiber to Oslo
Direct fiber path to the Oslo interchange and the Nordic backbone. Low-latency reach to most of Europe in under 25 ms.
Redundant power
Energy class A building, with N+1 power and connectivity. Backed up, monitored, and operated by people who know the building.
