DNOX CDN — European edge delivery

Network

Anycast is not used. Pick a node explicitly, or let edge.dnox.eu resolve by GeoDNS. Node hostnames are stable and safe to hardcode.

Quick start

Point a CNAME at the edge, set your origin, done. Free until 50 GB/month.

$ dig +short cdn.example.com
edge.dnox.eu.
nl1.dnox.eu.
87.199.199.192

$ curl -sI https://cdn.example.com/app.7f3a91.js
HTTP/2 200
content-type: application/javascript
content-length: 184320
cache-control: public, max-age=31536000, immutable
age: 41207
x-cache: HIT
x-served-by: nl1
vary: accept-encoding

Cache defaults

We do not rewrite your Cache-Control. If the origin sends none, the default is 4 hours for 2xx and 30 seconds for 404.

Compression

Brotli and gzip negotiated per request. Objects above 1 MB use Brotli 6, not 11 — the extra ratio was not worth the CPU on nl2/nl3.

Purge

$ curl -X POST https://api.dnox.eu/v1/purge \
    -H "Authorization: Bearer $DNOX_TOKEN" \
    -d '{"urls":["https://cdn.example.com/assets/*"]}'
{"queued":1,"nodes":11,"eta_seconds":8}

Purge is not atomic across nodes.

Propagation is usually under 10 s, but during that window one node may serve the old object while another serves the new one. If that breaks your deploy, version your filenames instead of purging. We would rather say this than pretend otherwise.

TLS

Certificates

Issued via ACME, renewed at 30 days remaining. Bring-your-own accepted as PEM, full chain, unencrypted key.

Protocol

TLS 1.2 and 1.3 only. 1.0 and 1.1 were removed in 2022 and will not come back. OCSP stapling is on by default.

HSTS

Off by default, on purpose. Once a client caches the header we cannot take it back for you — enable it when you are sure.
