Mission
CDNLog.com exists to make CDN logging easier to reason about across vendors, teams, and tools. The site emphasizes durable concepts: request identity, HTTP semantics, cache outcomes, timing boundaries, delivery guarantees, schema design, data quality, privacy, retention, and the connection between raw events and operational decisions.
The material is written for platform engineers, site reliability engineers, performance teams, security analysts, developers, and technical leaders evaluating edge observability architectures.
What this site is—and is not
Code and event examples illustrate implementation patterns. They are not production endpoints and do not imply that a corresponding hosted feature is available. Product-specific behavior should always be confirmed against the relevant provider documentation and your own configuration.
Editorial principles
Operational usefulness
Every field, metric, and architecture pattern should connect to a decision, investigation, or response.
Semantic precision
Similar names can hide different meanings. Timing boundaries, units, cache states, and null behavior must be explicit.
Vendor neutrality
Common models should enable portability without pretending providers expose identical capabilities.
Data minimization
More collection is not automatically better. Sensitive and high-cardinality fields need an approved purpose.
Evidence over claims
The site avoids fabricated benchmarks, partnerships, testimonials, service claims, and invented search metrics.
Accessible delivery
Pages are static, responsive, keyboard navigable, and designed to remain useful without accounts or forms.
Coverage areas
- CDN logging fundamentals and field selection.
- Edge log analytics and cross-provider normalization.
- Real-time log streaming, batch export, retry, and replay design.
- CDN monitoring, metrics, SLIs, SLOs, and alert quality.
- Cache analytics, HTTP timing, origin performance, and traffic analysis.
- Security detections, policy context, privacy, access, and retention.
- Developer schemas, event envelopes, data contracts, and validation.
Publication model
The Edge Signal Journal contains long-form field guides with visible publication and modification dates. Each article includes one carefully selected external editorial source and internal links to related implementation guidance. Category and tag archives keep topics discoverable without requiring a search form.
