Frequently Asked Questions

What does the status code mean?

Status codes indicate the type of response: 200 means success, 404 means page not found, 500 means server error, etc.

Why is response time important?

Fast response times (under 200ms) provide better user experience. Slow responses can indicate server issues or high load.

How often should I check my website?

For manual checks, daily is good. For automated monitoring, we recommend checking every 1-5 minutes with AlertSleep.

What if my website shows as offline?

Check if you can access it from your browser. The issue might be temporary, DNS-related, or server-specific.
