What Domain Monitor is
Domain Monitor is a web service for watching domains and connected infrastructure. Its monitoring suite covers websites, servers, SSL certificates, DNS, cron jobs, keywords, ports, and domain availability. Domain checks display WHOIS and domain-record information, track expiration, and provide advertised downtime and expiration alerts. Notifications can go through email, SMS, web, Slack, Discord, Twitter, webhooks, or Pushover. Team members may receive domain and SSL expiration notices as contacts without accounts. The free plan provides two monitors, one domain, one status page, two notification contacts, five-minute checks, and 14-day uptime monitoring. Pro lists 75 monitors and domains, five blacklist monitors, five domain-availability monitors, 15 SMS alerts, three status pages, and one-minute checks. Pro also adds custom HTTP statuses, DNS, response-time, and cron monitoring. New customers are listed at £6.39 a month for the first month, then 7.99 GBP monthly. Free traceroute, ping-test, and IP-address-finder tools are included.
