We've been using UptimeRobot for over six years to monitor our routers and default gateways across two sites, and it has consistently delivered excellent service. The email notifications are timely and reliable, ensuring we stay informed of any issues as they arise. The platform itself is well-designed, with an intuitive UI/UX that makes monitoring and managing alerts seamless. UptimeRobot has been a dependable tool in our infrastructure, and we highly recommend it for anyone needing efficient and hassle-free uptime monitoring.
