This ICMP Ping test on 2026-10-24 recorded an overall node response rate of 72%, below the 98% reference threshold; Unicom showed notably lower response and higher RTT than the overseas carrier, which is the anomaly observed here.
fred02.qzz.io Ping performance by network
Valid Ping response rate counts probes that received an ICMP echo response. P50 is the round-trip time at or below which half of valid responses completed; it is not packet-level loss.

Key findings
- Of 307 nodes, 221 returned a valid Ping response and 86 did not, giving a node response rate of 72%.
- Unicom's response rate was 39.7% (29 of 73 nodes), 60.3 percentage points below the overseas carrier's 100%.
- Unicom's median RTT was 381 ms with P90 at 781 ms, versus 3 ms median and 51 ms P90 overseas, a 378 ms median gap.
- Telecom and Mobile returned response rates of 83.9% and 72.2%, with median RTTs of 238 ms and 198 ms, both above the overseas carrier.
Improvement recommendations
- The Ping response rate is 0%, below the 98% review threshold. Retest the unanswered probes, then use TCPing or HTTP checks to distinguish ICMP handling from application reachability if the same probes remain unanswered.
