Using network namespaces for ipv4 only
The problem I use the Ookla Speedtest CLI in a cron job to get an idea of the speed of my internet connection (Verizon FIOS), and spot if there are problems. Why? Because why not :-) It let’s me draw graphs like this. However, recently I was starting to get error messages that the command wasn’t able to reach speedtest.net to get the configuration. It wasn’t happening every time; sometimes it would go hours without issue, other times it would fail 3 or 4 times in succession.
