About NWS's NWS Alerts
NWS's NWS Alerts provides active weather alerts and warnings for the US. The National Weather Service (NWS) is a US government agency under NOAA. The NWS Alerts is used by developers worldwide for weather alerts, warnings, hazard notifications, emergency planning.
Probecast monitors the NWS Alerts from 4 global regions (US West, US East, Europe, Asia Pacific) every 300 minutes, tracking uptime, latency and regional availability. Our real-time monitoring helps developers and teams understand the current health of NWS's NWS Alerts and get alerted the moment service degrades.
Why monitor NWS Alerts?
If your product depends on NWS Alerts for critical features, an outage on NWS's side is an outage on your product. Probecast detects NWS Alerts incidents before your users do, giving you time to communicate with customers, fall back to alternative services or pause background jobs gracefully.
