Global CDN & Network Performance Leaderboard

Name: CDN & Cloud Provider Network Performance Leaderboard
Creator: idcd

Based on 24 real probe nodes, updated monthly

Data period: 7/2026 · Update frequency: probed every 5 minutes, aggregated monthly

This Month's Picks

Data collected across all probes in month 7, sorted by global P50 ascending. P50 is the median response time — lower is better.

Methodology: All latency data is collected from idcd's global real probe nodes using HTTP GET requests to each CDN's standard benchmark endpoint, measuring TCP-handshake-to-first-byte time (TTFB). Each node probes every 5 minutes; monthly figures use P50 (median) to eliminate jitter. Availability is derived from DNS resolution success rate and TCP reachability.

All boards

Focused boards computed from real nationwide probe data — open a board for details and window switching.

CDN Latency Leaderboard

Global and mainland-China latency rankings for major CDNs from real probe nodes, sorted by P50/P95 latency, updated monthly.

CDN Availability Leaderboard

Uptime comparison across major CDN providers over the sampling window, ranked by availability percentage to highlight reliability.

CDN Week-over-Week Movers

CDNs ranked by their P50 latency change versus the previous period, biggest improvements first — a quick read on who sped up or slowed down.

Provincial Network Quality

Network quality across China's provinces from our own probe nodes, ranked by availability then P50 latency to reflect the real local experience.

Node Tier Comparison

Head-to-head network performance across node tiers — home broadband, datacenter, mobile, and small VPS — sorted by P50 latency.

Monthly Coverage Growth

Provinces ranked by month-over-month growth in the number of covering probe nodes, tracking the geographic expansion of the probing network.

Carrier Comparison

Head-to-head cross-province network quality for the big-three carriers — China Telecom, Unicom, and Mobile — ranked by availability then P50 latency. Based on each node's declared carrier (falling back to ASN inference), aggregated anonymously without naming any single node.

Province × Carrier Heatmap

A province-by-carrier heatmap of network quality, showing each carrier's availability and latency in every province. Cells with too few samples or nodes are withheld to keep single-user nodes anonymous.

Cloud Provider Latency Leaderboard

Latency ranking of major cloud providers' public entry points measured from real probe nodes, sorted by P50 latency low to high.

Cloud Provider Availability Leaderboard

Availability comparison of major cloud providers over the sampling window, sorted by uptime percentage high to low.

Public DNS Resolver Leaderboard

Resolution-latency ranking of major public recursive DNS resolvers, sorted by lookup time low to high to help pick a faster resolver.

Cross-Border Access Leaderboard

Cross-border access quality faceted by the probe node's country/region; overseas nodes shown by default, sorted by P95 latency low to high.

Contributor Node Stability Leaderboard

Community contributor nodes ranked by their own uptime, computed from the node lifecycle log — thanks to everyone keeping capacity online.
