Screenshot change in ping time I realized the high maximum IPv4 ping times never showed up when I redid the measurement by hand, and IPv4 was the first test in the crontab line.

So I guess a lot of scripts ping every 5 minutes and it's a bit congested at exactly that time. I added a small delay before the start of the measurement and suddenly the strange peaks are gone.
