What is Uptime Monitoring?
Uptime monitoring means checking whether your website is reachable and responding correctly at regular intervals. When a check fails, you get alerted immediately — so you can fix the problem before most visitors are affected.
Websites go down for many reasons: server crashes, deployment errors, DNS issues, expired certificates, or upstream provider outages. Without monitoring, you often find out from a customer complaint — or worse, lost revenue.
Uptime Monitor checks your websites every minute from multiple global locations, tracks response times, and calculates uptime percentages — giving you the data you need to maintain reliability and hold hosting providers accountable.
