What is 24/7 uptime monitoring?

24/7 uptime monitoring means a service checks your website or server continuously, day and night, including weekends and holidays. Outages don't respect office hours, so neither should your monitoring.

A proper 24/7 monitor does three things for you at all times:

• Detects downtime fast, typically within a minute or two of the first failure
• Verifies the problem is real, usually by rechecking from a different location so a single flaky network doesn't page you at 3 AM
• Sends the alert to wherever you actually are, whether that's email, Slack, SMS, PagerDuty, Opsgenie, or a custom webhook

Oh Dear does exactly that. Checks run every minute from multiple locations, every downtime is verified before we alert, and notifications go out instantly through more than a dozen channels. Start monitoring for free, no credit card required.
