How to detect is it dns or http down?
Posted by linuxfan, 08-01-2009, 10:26 AM If i put domain.com on uptime checker,and downtime is detected,downtime will be reported if dns is down or if http server is down.So question is what i need to do to see what exactly went down?For network uptime i can ping ip adress,but for these two i really don't know.

If the DNS resolves and gives a reply, but website does not open, then the web server may be down. If the DNS server is on another server, then the chances are that the entire server in which the web server resides may be down.
