This ICMP Ping test against dns.google on 2026-09-29 recorded an overall node ICMP response rate of 79.1%, below the 98% reference threshold. Telecom stood at 51.6%, a 48.4 percentage-point gap from overseas at 100%, which is the clear anom

dns.google 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.

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

  • Overall response rate was 79.1%: 250 of 316 nodes returned a valid Ping response, leaving 66 unanswered nodes.
  • Telecom had the lowest response rate at 51.6% (66/128), with a median RTT of 235 ms and P90 of 316 ms.
  • Unicom, mobile and overseas recorded 96.1%, 98.7% and 100% response rates respectively, all near the threshold.
  • Overall RTT was 128 ms at P50 and 308 ms at P95; mobile showed a 56 ms median and overseas 1 ms, indicating differing RTT distributions across carriers.

Improvement recommendations

  • The Ping response rate is 79.1%, 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.
  • China Telecom trails overseas by 48.4 percentage points in response rate. Retest both groups with the same probe set, then investigate the affected network or endpoint only if the gap repeats.

These results describe this distributed test only and do not establish long-term availability, security, or a root cause.
