Why does PingBench test both ICMP and TCP port 443 in MTR route checks?
Carrier firewalls and anti-DDoS scrubbers occasionally deprioritize ICMP echo packets while forwarding TCP-443 application traffic over primary low-jitter trunks.
On PingBench, we detail how to detect detoured Asia BGP routes by inspecting AS-path hop counts and comparing Singapore (AAG/APG/SJC/ADC) against Tokyo (APG/SJC2) using official Looking-Glass hosts.
This PingBench profile references official vendor specifications retrieved 2026-11-12 (https://www.vultr.com/pricing/) and remains noindexed pending raw ISP telemetry.

A genuine direct route from Ho Chi Minh City or Hanoi into Singapore stays within ASEAN/APAC exchange hops, whereas budget transit circuits that hairpin via US West jump above 140 ms RTT on mtr traces.
Maintaining automated nightly snapshots or standby IaC templates in Tokyo lets engineering teams pivot traffic northward over APG/SJC2 whenever southward cables enter scheduled repair.
