SiteUptime
SiteUptime monitors website and server availability and alerts users when downtime is detected.
What SiteUptime is
SiteUptime monitors website and server availability and alerts users when downtime is detected. Checks can run every 2, 5, 15, 30, or 60 minutes, depending on account and monitor settings. Monitoring options include HTTP, SSL, web page content, DNS, POP3, SMTP, password-protected HTTP, custom TCP ports, FTP, and ping. The service checks from multiple geographic locations and can verify a failure from another location before alerting. Accounts include online uptime statistics and monthly reports, with graphical reports on paid plans. Standard and Pro users can use the REST and JSON API to manage monitors and access uptime data, including connections through systems such as Zapier. The Free plan provides one monitor, slower checks, 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 card or PayPal details.
