SiteUptime

Website and server monitoring service.

Visit SiteUptime

SiteUptime is a website and server monitoring service that checks availability from 11 locations across 4 continents. It solves the problem of undetected downtime by verifying failures from a second geographic location before sending an alert, which reduces false positives. The service supports monitoring of HTTP, HTTPS, DNS, POP3, SMTP, FTP, and custom TCP ports, as well as ping and web page content.

Key capabilities include configurable check intervals (every 2, 5, 15, 30, or 60 minutes), email, SMS, and phone call alerts, and a REST API. Paid plans add features such as DNS monitoring, public status pages, webhooks, failure traceroutes, sub-user accounts, blackout scheduling, and graphical reports. The service provides monthly uptime reports and online statistics through a control panel.

The service is aimed at website owners and system administrators. It offers a free plan with one monitor and 30-minute checks. Paid plans are seat-based, with Standard and Pro tiers providing 3 or 6 monitors respectively, 2-minute checks, and SMS or call credits. Additional monitors can be purchased per month, and extra SMS credits are available in bulk.
