Polymarket API latency and status

Polymarket's CLOB answers its midpoint endpoint at 102 ms p50 over warm connections (24h). The API fronts Cloudflare, so brief origin trouble often appears here as a latency spike before it ever becomes an error, which makes the latency series a useful early status signal. The uptime panel above is a live Polymarket API status check, computed from probes fired every 5 seconds from three regions, so it reacts within seconds of a real outage instead of waiting for user reports. For how the CLOB behaves under bursts, see the pm-rate-limits bench.
