Connectivity Issues with Cloudflare R2 Files for True Internet Users in Thailand

Hello everyone, We’re experiencing an issue where a customer using True Internet in Thailand is unable to reach our Cloudflare R2 files. Here are some details of our troubleshooting so far: Issue Summary: Customer ISP: True Internet (Thailand) Problem: Accessing Cloudflare R2 files fails for the customer, though the same files are accessible via other networks. Troubleshooting Steps Taken: - DNS Verification: Confirmed that DNS resolution for the R2 endpoint is working (using public DNS like 8.8.8.8 shows correct resolution). - Traceroute Tests: Ran traceroute from the affected network. The results show timeouts and latency spikes at certain hops, suggesting potential routing or peering issues between True Internet and Cloudflare’s network. - Cross-Network Testing: Access from other ISPs (including mobile networks) does not reproduce the issue, further indicating that the problem might be ISP-specific. Points for Discussion: - Has anyone observed similar issues with True Internet or in the Thailand region? - Are there known routing or peering challenges between True Internet and Cloudflare’s services? - Any recommendations for further diagnostics or configuration checks on our Cloudflare setup? Looking forward to your insights and suggestions.
