External reliability

See availability and TLS health from the outside.

Observe external HTTP availability, response behavior, hostname validity, certificate chains, and expiry state from one endpoint record.

Checks

External checks reflect what a visitor can reach instead of relying only on internal server state.

Outside-in visibility

Know when customers feel an outage

Monitor availability and TLS health from outside your network, then route useful alerts to the people who can act.

  • Accountable alerts

    01

    Route downtime, TLS validity, and response-condition alerts with the affected endpoint and check context attached.

    alerting

  • Availability history

    02

    Review availability, downtime, and response history without separating performance from certificate state.

    history

  • External check locations

    03

    Compare external observations across check locations to isolate regional reachability and latency differences.

Operating sequence

From endpoint check to accountable alert.

Define the service, observe availability and TLS state, then send the failure context to the team that owns recovery.

Platform fit

Connect external symptoms to certificate context

Availability checks and TLS validation stay tied to the monitored endpoint and its certificate record.

Digital trust, continuously verified.

Put tls & uptime monitoring into operation.

Add the first endpoint and keep availability, response behavior, and TLS validity attached to one accountable record.

  • External availability and response checks
  • Hostname, chain, and expiry validation
  • Alerts routed with the failing condition
