You Can't Check 24/7
Your website can go down at 3 AM on a Sunday. Unless you're checking constantly, you won't know until someone complains - or until you lose customers.

The Problem with Manual Checking
By the Time You Know, It's Too Late
If you find out your site is down by visiting it yourself, how long was it down before that? Minutes? Hours? Automated monitoring catches issues immediately.
Regional Issues Go Unnoticed
Your site might work fine for you but be down for users in other countries. AlertsDown checks from multiple locations to catch regional problems.
How AlertsDown Website Monitoring Works
AlertsDown sends HTTP requests to your website at regular intervals - as frequently as every minute. We check that your server responds and returns the expected status code.
When your site doesn't respond or returns an error, we immediately send you an alert via your preferred channel. You'll also get notified when your site comes back online, so you know the issue is resolved.
