I was about to update the custom domain how-to, so I thought I'd work through its steps again.
The wikidot IP address has changed, so I pinged it. Here's what I get:
I looked up the error message, and here's what I find:
Essentially, this error message indicates that your host did not receive the ping message back from the destination device within the designated time period. Assuming that the network connectivity is okay on your system, this is typically an indicator that the destination device is not connected to the network, is powered off, or is not configured correctly.
Any concern with this?
