​
General

​
What is Tenbyte CDN?

A global content delivery network with anycast routing, edge caching, image optimization, signed URLs, and a REST API. Edge nodes serve cached responses close to the user; origin only sees cache misses.

​
How does it speed up my site?

Three levers: shorter network distance (edge PoP near user), cached responses (no origin round-trip on hits), and HTTP/2 + HTTP/3 multiplexing.

​
What protocols are supported?

HTTP/1.1, HTTP/2, and HTTP/3 (QUIC) on the client side. Origin pulls support HTTP/1.1 and HTTP/2.

​
Caching

​
What is the default cache TTL?

The edge respects your origin’s Cache-Control: max-age and Expires headers. To override, configure a cache rule.

​
Why do I keep seeing x-cache: MISS?

Common causes:
  • Origin sends Cache-Control: no-store, private, or max-age=0.
  • Each request has a unique query string and cache-key includes the query.
  • Different Vary headers fragment the cache.
  • Object exceeds the max cacheable size.
Inspect the response with curl -I and check the cache rule for the path.

​
How do I bust the cache after a deploy?

Use Purge by Pattern for a path or wildcard, or Purge All. Both are available via the API: 
curl -X POST "https://api.tenbyte.io/cdn/distributions/$DISTRIBUTION_ID/purge" \
  -H "Authorization: Bearer $TENBYTE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"paths": ["/static/*"]}'

​
Security

​
Is my content secure?

TLS 1.2/1.3, optional WAF, token-authenticated signed URLs, and IP / referrer / country rules. DDoS mitigation runs at the edge.

​
How do I protect a private path?

Layer it: token authentication for time-limited URLs, plus referrer or IP rules so a leaked URL still can’t be replayed from arbitrary networks. See Access rules.

​
Where do I rotate the signing secret?

Per access rule, in the console. Walk through the rotation runbook before swapping in production.

​
Operations

​
How do I monitor traffic?

Analytics — bandwidth, request count, cache-hit ratio, and response-class breakdown. Pull the same metrics from the API for your dashboards.

​
Can I run multi-region or multi-CDN?

Yes. Tenbyte CDN routes to the healthiest edge automatically. For multi-CDN setups, point one CNAME per provider and use a steering DNS (Route 53, NS1) for failover.

​
What happens during a regional outage?

Traffic shifts to the next-best PoP via anycast and health checks. Origin is only contacted on cache miss, so cached content keeps serving.

​
API and automation

​
Where is the API reference?

CDN API reference. The OpenAPI spec is published at https://raw.githubusercontent.com/vidinfra/open-api-docs/refs/heads/main/cdn-openapi.json.

​
How do I authenticate API calls?

Bearer token in the Authorization header. Generate one in Organization → API Keys: 
curl -H "Authorization: Bearer $TENBYTE_API_TOKEN" https://api.tenbyte.io/cdn/distributions

​
Are there rate limits?

Yes. Standard accounts get a generous per-minute quota that’s enough for normal automation. Bulk imports or large purge fan-outs should batch and back off on 429.

​
Are webhooks supported?

Yes — for purge completion, certificate events, and traffic alerts. Configure in the distribution settings.

​
Billing

​
How is Tenbyte CDN billed?

Pay-as-you-go on bandwidth and requests. No minimums, no long-term commitment. See Billing.

​
Does cache miss traffic cost more?

Egress from origin to edge is metered separately. Tuning cache rules to raise hit ratio is the cheapest way to lower bills.

​
Are purges billed?

Purges themselves are free. The next request after a purge is a cache miss and counts as origin egress.

Support

24/7 support via console chat and email. Critical incidents get priority routing.
