What is the name of the domain?
The issue is not specific to a single domain but affects all traffic routed through 172.67.215.44.
What is the error number?
There is no specific error number associated with this issue.
What is the error message?
No error message, but experiencing high latency (ping >300ms) and packet loss (~10%) when connecting to Cloudflare services.
What is the issue you’re encountering
I am encountering significant latency and packet loss when routing traffic through the Hong Kong (HKG) data center.
What steps have you taken to resolve the issue?
I am encountering significant latency and packet loss when routing traffic through the Hong Kong (HKG) data center. Based on a series of tests, the issue appears to occur at Cloudflare’s 172.67.215.44, as shown in the WinMTR logs.
Key observations:
Latency spikes from 3ms to >500ms on this hop.
Packet loss of ~10%.
Cloudflare’s status page shows HKG as “Partially Re-routed.”
- I confirmed that my local ISP connection is stable with no issues (1ms ping to my router).
- Switched DNS to 8.8.8.8 to rule out DNS resolution issues.
- Performed WinMTR tests to the affected Cloudflare IP (172.67.215.44).
- Checked Cloudflare’s status page and found that the Hong Kong (HKG) region is marked as “Partially Re-routed.”
- Verified the speed test from Cloudflare’s platform (speed.cloudflare.com), which shows normal performance.
- Reached out to my ISP, who confirmed no issues on their end.
What are the steps to reproduce the issue?
Run a traceroute or WinMTR test to any domain routed through Cloudflare, such as speed.cloudflare.com.
Observe the increased latency and packet loss at the hop 172.67.215.44.
Compare results across different times of the day to note consistent high latency during peak hours.
Additional Context:
This issue affects services that rely on low latency and stable packet delivery, such as online gaming, video streaming, and real-time communications. It seems to be directly related to Cloudflare’s routing in the HKG region.
