When traveling, in case my destination country does not have a Mullvad server, I often need to figure out which of the servers in surrounding locations have the lowest latency. This usually involves searching for servers around me, and then a lot of pinging, which, having done it twice, I decided to automate.
The IVPN client also has this feature, which is another selling point for customers of Mullvad looking for a provider which still supports port forwarding.
