Is your website down? Is one of your domain names about to disappear(because someone forgot to update their email address with the registrar [oops])? Binary Canary to the rescue! I consider myself to be pretty organized. However, details, even important ones, do occasionally slip through the cracks. The above scenarios happened to me within days of each other – and I would have avoided significant headaches had I been subscribed to their service at the time. In addition to monitoring the up-state of your website and checking domain registry status, their premium options also monitor FTP, various email protocols, PING, DNS, SSL certificates, TELNET, and ports. Notifications can be configured to be sent out via any combination of email and SMS to any number of designated contacts. Highly recommended.
