About the author

I'm a system architect/research coordinator at the RIPE NCC, where I work in the science group. I'm a chemist by training, but have been working since 1998 on Internet related things, as a sysadmin, security consultant, web developer and researcher. I am interested in technology changes (like IPv6 deployment), Internet measurement, data analysis, data visualisation, sustainability and security. I'd like to bring research and operations closer together, ie. do research that is operationally relevant. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.

Distribution of RIPE Atlas Probes

Distribution of RIPE Atlas Probes

As the RIPE Atlas network continues to grow, it's useful for ambassadors and potential probes hosts to easily see where we already have probes deployed and where we'd like more probes installed. We created a few useful maps to help with this.
