curl.se Traffic Analysis: 2TB/day, Where's All the Traffic Coming From?

The curl.se website handles 62.95 TB of traffic per month, averaging over 2 TB per day and peaking at 3.41 TB. While detailed logs are unavailable, data shows that of 12.43 billion requests, only 1.12 million were curl package downloads (less than 10% of total traffic). The vast majority of traffic (99.77%) is handled by the Fastly CDN cache. However, widespread use of HTTP/1.1 and TLS 1.2 suggests a significant amount of non-browser traffic, possibly from bots or other tools. Analysis indicates that 207.31 million downloads of 100KB-1MB files (likely CA certificates) could account for a large portion of the remaining traffic. Traffic is evenly distributed globally, unlike previous concentrations in China.
