An external uptime monitor checks your site at regular intervals and alerts you the moment it becomes unreachable.
Why External Monitoring Matters
A monitor checking from outside your own network catches outages your own browsing habits would never reveal, since you might not visit your site at the exact moment it goes down.
What to Monitor Beyond the Homepage
Checking critical pages specifically — a checkout flow, a login page — catches issues a homepage-only check might miss entirely.
Setting Up Alerts That Actually Reach You
Email alone can be missed during a busy day — pairing it with SMS or a messaging app notification ensures a real outage gets your attention quickly.
