CDN Latency Diff
Compare baseline vs candidate CDN latency across regions with diffs and budgets.
Paste comma or tab separated values: Region, Baseline, Candidate, SLO.

Overview
Benchmark baseline vs candidate CDN latency directly in the browser. Track per-region diffs, highlight regressions, and surface SLO breaches before rollout.
How to use
- Start with the sample regions or paste measurements from your probes.
- Adjust SLOs or exclude rows that do not belong in the comparison.
- Review diff and % change columns plus the summary cards.
- Export CSV when you need to share the measurement set.
Use cases
- Compare two CDN vendors before contract renewal.
- Validate latency after enabling HTTP/3 or new edge POPs.
- Spot regional regressions during incident response.
Tips & knowledge
- Look at both raw Δms and % change to capture tail shifts.
- Measure at consistent times to avoid peak-hour volatility.
- Collect multiple passes and average to reduce jitter noise.
