Pingometer is a service that monitors the uptime, downtime, and performance of websites.
You can monitor anything: HTTP, HTTPS, RUM, DNS, IMAP, POP3, SMTP, TCP, UDP, API, or Transactions.
Our platform performs real-time checks from locations around the world -- 24/7/365. If an outage occurs, it is confirmed before alerts are sent (no false positives). You get notified via email, text, voice, Twitter, or webhook. More Info »
It's easy to setup (no installation), has a pleasant UI, and is simple to use.
