Edge cache
Tiered caching with a shield layer in front of your origin. Purge by URL, prefix or surrogate key in under 300 ms, network-wide.
- stale-while-revalidate
- Brotli & Zstd at the edge
- Range request collapsing
Anycast content delivery network
Serve every request from the nearest city.
Stratum Edge caches, routes and terminates traffic in 214 points of presence. Your origin only sees what the edge can't answer on its own.

The network
One address. Two hundred and fourteen answers.
Every PoP announces the same anycast prefixes, so routing happens in BGP rather than in DNS or a client SDK. If a site loses power, the prefix is withdrawn and the next-closest PoP picks up the session.

Platform
Four things, done properly.
No marketplace, no add-on tiers. Every account gets the whole platform; you pay for the traffic you move through it.
Load balancing
Weighted origin pools with active health checks from three continents. Failover decisions are made at the PoP, not at a central controller.
- Session affinity
- Origin steering by geo
- Automatic retry budgets
TLS & WAF
Free managed certificates with ACME renewal, or bring your own chain. Rule sets update without a config deploy.
- TLS 1.3, mTLS to origin
- OWASP core rule set
- Rate limiting per key
Real-time logs
Structured request logs streamed within two seconds of the response, to S3, Kafka, or an HTTP endpoint you control.
- Configurable field set
- Sampling from 0.1 %
- 90-day retained metrics
Getting started
Point a hostname at us. That's the migration.
Most teams move a production hostname in an afternoon. Pull traffic back with a single DNS change if you don't like what you see.
- 01Add the hostname and origin in the console or with the CLI.
- 02Verify ownership with a TXT record; we issue the certificate.
- 03Move the CNAME to your assigned anycast endpoint.
