Rust uptime monitor hits 130K checks/sec per core with custom HTTP client

Uptimepage is an open-source uptime monitor written in Rust that ships as a single 23 MB binary. It uses Postgres for relational data and ClickHouse for time-series check results, avoiding common scaling pitfalls. A custom HTTP client built on hyper and rustls achieves 130K checks per second per core with per-phase timing.
