# What is 24/7 uptime monitoring?

[24/7 uptime monitoring](/features/website-uptime-monitoring) means a service checks your website or server continuously, day and night, including weekends and holidays. [Outages don't respect office hours](/uptime-statistics), 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](/register), no credit card required.
