Perform a Traceroute
In the event that you’re unable to access a website and/or domain, one step to debug this issue is to perform a traceroute.
Mac OSX
- Open up the OSX terminal app from under Applications/Utilities.
- When terminal opens, type the following command:
traceroute domain.com
note: replace ‘domain.com’ with the actual domain name to which you want to trace.
If the traceroute is unable to follow the hops of a packet from your computer to the target domain, please review where the last successful hop was. Often times it will be somewhere between your computer and our servers, such as your ISP, or another provider between your ISP and our ISP. If you are unsure, please submit a support ticket and paste the output of the traceroute.
Example output:
$ traceroute ion.planetargon.com
traceroute to ion.planetargon.com (198.145.242.226), 64 hops max, 40 byte packets
