A friend of mine in Austria recently sent me something strange. He’d connected to Proton VPN’s Eritrea server, a country in the Horn of Africa, and was getting sub-40ms ping to Austrian servers. For context, Eritrea is roughly 5,000 kilometers from Austria. Even with a perfect fiber optic path, you’d expect latency well north of 60ms for a round trip of that distance, and real-world routing would push it higher. Sub-40ms to a European server, while supposedly tunneled through East Africa, didn’t add up.
