Before you check

One-time checks are helpful, but outages happen between them. Continuous monitoring alerts you fast.

Why monitoring beats one-time checks

A single check is a snapshot. Continuous monitoring catches the next outage, tracks recovery time, and gives you proof for providers.

  • Checks every few minutes with alert delivery.
  • Incident timelines with exact timestamps.
  • SSL and DNS visibility without manual work.
