This ICMP Ping test against 85.149.220.250 on 2026-09-19 recorded an overall node ICMP response rate of 82.7%, below the 98% reference threshold, with 55 unanswered nodes. Median RTT was 97 ms and P95 was 201 ms.

85.149.220.250 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

  • The overall node ICMP response rate was 82.7%: 263 of 318 nodes returned a valid Ping response, leaving 55 unanswered nodes.
  • The telecom carrier showed a 70.2% response rate, 29.8 percentage points below the overseas carrier at 100%, the lowest among the carriers.
  • Telecom RTT was 95 ms at P50 and 135 ms at P90, while mobile was 82 ms at P50 and 109 ms at P90, giving mobile a lower RTT distribution.
  • The overseas carrier reached a 100% response rate but its P90 was 245 ms, noticeably higher in the upper RTT range than other carriers.

Improvement recommendations

  • The Ping response rate is 82.7%, 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 29.8 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.
