Uptime Robot
Add a new section to your client maintenance reports with WP Client Reports Pro that shows you are on top of hosting issues and that you will always know before your client that their website is down.
Uptime Robot is a helpful service that checks in on your websites every 5 minutes to make sure they are online. Their free tier is generous allowing you to add 50 websites and get checks for each of those every 5 minutes. If an issue is found they will email you and can even text you for a small fee. They also offer a Pro level that offers more checks and more frequent monitoring.
