Stéphane Bortzmeyer#RIPEduca starts in less than one hour https://www.ripe.net/support/training/ripe-ncc-educa Today, RIPE Atlas probes!
One last coffee and I stand ready.
Soon to start, #RIPEduca. Expect some live-tooting about RIPE Atlas probes, Internet measurements and etc, if the proprietary bloatware Adobe Connect works.
Now, RIPE Atlas probes and Internet Exchange Points, by Willem Toorop and Emile Aben.

A study of Internet connectivity in Canada
The Canada interconnectivity survey was done by analysis *existing* RIPE Atlas measurements (by default, measurement results are public).
Among the questions: how much of canadian traffic stays inside Canada? Between unicast machines (gov. Web servers for instabce) hosted in Canada? Between a probe in Canada and a anycast DNS server which has instances in Canada?
Usual problems of Internet measurements: traceroute with non-responding routers, routers replying with RFC 1918 (private) IP addresses, geolocation inperfect...
Ping @angristan about the ability of the US to shut down the Internet: some Canada traffic goes through the US.
Result: 64 % of "canadian" traceroutes go through the US. (And these traceroute are often faster, which may be the reason: international links are upgraded more often; another reason is the lack of peering in the country)
Only 29 % of canadian governement sites are hosted in Canada. (And traceroute to them often go through the US.)
