Uptimepage is hosted uptime monitoring and public status pages for teams, and I build it. Checks run every 60 seconds from five regions; a failing check opens an incident and posts it to your status page. Eight check types: HTTP, TCP, ping, DNS, TLS and domain expiry, cron heartbeats, browser logins. Alerts to Slack, Telegram, PagerDuty and webhooks, with flap suppression so one bad probe never pages you. As code via REST API, Terraform or MCP. One Rust binary on Postgres and ClickHouse, AGPL.
