What SiteUptime is

SiteUptime monitors website and server availability and sends alerts when it detects downtime. It supports HTTP, SSL, web page content, DNS, POP3, SMTP, password-protected HTTP, custom TCP ports, FTP, and ping monitoring. Checks can run every 2, 5, 15, 30, or 60 minutes depending on the account and monitor settings. The service checks from multiple geographic locations and verifies failures with another location before alerting, to reduce false positives. Accounts include online uptime statistics and monthly reports; paid plans add graphical reports. Standard and Pro users can use the REST and JSON API to manage monitors and access uptime data, including through internal or third-party systems such as Zapier. Free includes one monitor, checks every 30 or 60 minutes, email alerts, reports, and 11 monitoring locations. Standard costs $10 a month, billed $96.00 yearly; Pro costs $20 a month, billed $192.00 yearly. Additional monitors cost $2 per month each. Free registration does not require credit card or PayPal details.
