Subject: High Latency Issue from China Unicom to Cloudflare San Jose (AS13335)

Dear Cloudflare Support Team,

I am experiencing a severe latency issue when accessing Cloudflare servers (AS13335) in San Jose from China Unicom (AS4837).

Issue Details:

• Previous latency: ~181ms
• Current latency: ~642ms
• Affected range: Between AS13335 to AS13335
• This issue is significantly impacting Chinese users, making it difficult or even impossible to use Cloudflare services properly.

Steps to Reproduce:

1. Running traceroute or MTR from China Unicom (AS4837) to Cloudflare San Jose (AS13335).
2. Observing a dramatic increase in latency within AS13335, suggesting a potential issue within Cloudflare’s network or its upstream providers.

Expected Outcome:

I kindly request Cloudflare’s engineering team to investigate this issue and coordinate with relevant network providers to restore normal latency levels.

If additional information is needed, I can provide MTR, traceroute, or other relevant data.
