Last month we covered the 2015 leap second ahead of the insertion of a leap second at the very end of 2016. As stated previously, leap seconds can trigger poorly-tested code paths; leap second handling always unearths bugs and issues. This one was no exception!

In this article, we give one example of the possible communities that are now easier to build around RIPE Atlas probes. With the tagging of similar probes, existing communities can use additional tools for creating and analysing RIPE Atlas measurements, such as "IXP Country Jedi", to create their o…
