Without downtime alerts, you are the last to know
Your website goes down and you only find out when a customer emails you hours later.
A DNS change or expired certificate quietly takes your site offline - and nobody on the team notices.
You check your site manually once a day and hope nothing breaks in between.

How website monitoring alerts work
Add your website URL
Enter any URL you want to monitor. No code changes or agents required - just paste a URL and you are ready.
Choose your alert channels
Pick where you want to receive website down alerts - email, Slack, Telegram, webhooks, or any combination.
Get notified when your site is down
Your site is checked every minute from multiple regions. The moment something breaks, you get an instant downtime notification with the details you need to fix it.
Why instant downtime alerts matter
Website downtime directly impacts revenue, user trust, and search engine rankings. Every minute your site is unreachable, potential customers leave and may never return. Studies show that even brief outages can cost businesses thousands in lost sales, and repeated downtime erodes the reliability users expect.
Without automated website downtime notifications, teams rely on manual checks or wait for user complaints. By the time someone reports the problem, the damage is already done - lost transactions, failed API calls, and search engine crawlers hitting errors that quietly hurt your rankings.
Instant downtime alerts close this gap. When your site availability monitoring detects an issue, you are notified within seconds - not hours. Faster detection means faster resolution, shorter outage windows, and less impact on your users and your business. The difference between a 5-minute outage and a 2-hour outage often comes down to whether anyone was watching.
