London and Chicago are live. Sentinel now checks every site from 6 regions on every plan. Not “check from one place, then confirm somewhere else if it fails.” Every region. Every check. 14 is the goal. sentinel.rootstuff.io

The Sentinel free plan just got a lot bigger. Uptime, SSL, DNS, domain expiry, keyword, ping, port, and JSON API checks are all free now. The same checks paid plans run, on 10 monitors at 5-minute intervals. You also get read-only API and MCP access, so you can point Claude or any MCP client at your monitors and ask what's down. The Mac menu bar app works on free now too. No credit card. sentinel.rootstuff.io
