DNS updates are a pain. They test your patience as you wait “up to 72 hours for your changes to propagate,” and often you need to know when it’s done. If you’ve ever moved from one web host to another, you know how tricky it is to make the transition seamless. You have to get the site working on the new server, put the active copy of the site into maintenance mode, then update your DNS settings, and hope everything works out fine.
In case something goes awry, it’s a good idea to be there, ready, when it happens. That’s where DNS Pinger comes in. Just enter your domain name, along with your email address, and the service will automatically ping your site every three minutes. You will receive an email alerting you the minute the DNS update is complete.
