Wow, this is an incredible deep-dive into the real-world side effects of post-quantum cryptography (PQC)—something most devs or users won’t even realize is happening under the hood. It’s wild how a slightly bigger TLS handshake due to Kyber can cause such elusive network bugs, especially over VPNs or constrained MTU environments. The fact that you tracked this down by comparing cURL vs browser-level handshakes is top-tier troubleshooting.

Also, the MTU fragmentation issue really highlights how fragile things can get when cryptography moves ahead of network standards. PQC is crucial for the future, but this kind of debugging story is a clear reminder that implementation matters just as much as theory.

Thanks for sharing this — I bet a lot of people are struggling with weird loading issues and have no idea it's due to oversized TLS packets. You just saved folks hours (maybe days!) of head-scratching.

Post-quantum cryptography is too damn big. (2024)
