Prague is the most popular European destination for IETF. Other locations (Berlin, London, Paris and Stockholm) have so far hosted only two meetings each. In Prague, on the other hand, we can look forward to the next conference of this organization in the spring of 2019.

Just like two years ago, this time I’ve also decided to show the 99th IETF in numbers and charts. This year, a total of 1,230 participants arrived in person, some of whom took with them to Prague their better halves or offspring. In addition, 506 people were present at the meeting virtually as remote participants.
People from 59 countries came to the IETF in Prague, mostly from the USA (453), Germany (116) and China (95). Sixteen countries, such as Bangladesh, Lesotho, or Venezuela, we represented by just one participant. As the most exotic territory from which one participant came to Prague, I consider the United States Minor Outlying Islands (UM).
The last graph shows the day of the IETF visitors check-in. It makes sense that it peaked on Sunday, July 16. If all visitors were to fly to Prague on the same plane, the biggest airliner A380 would not be enough.
