Caused by a temporary outage in your internet/DNS, all we would be able to do is sit there and wait for your internet to come back on, which might not be a bad idea.

Maybe I was not clear. When this happens, the application crashes. This is not a handled error so even if the network/internet comes back up, it won't matter. You need to manually terminate the execution and restart the program. So though we could talk about caching DNS results or what not, this error needs to be handled maybe with a minute delay and try again and avoid outright crashing.
