DNS Monitoring service?
I have a client who decided it was better to handle their own DNS for their website. Now there have a been a few DNS outages and of course I am blamed as nobody could get to the site. I already have a monitor service for the site but when DNS is down it does not report that it is DNS over a site outage. Can anyone recommend a low cost service that will monitor DNS? I need something that gives a report to show that it is DNS, how many tries and how long it is out.
