Frequent downtime has a notable impact on your website, because visitors are rejected and it's likely that they won't come back.

Depending on your choice, the tool can check the status of your website every 1 minute to 1 hour. Using the uptime monitoring service, you can even check for yourself whether your web host is able to keep the commitment of 99.9% or 100% uptime.
