This week marks the 30th anniversary of the meeting that became the very first edition of IETF meetings now held three times per year. On 16-17 January 1986 in San Diego, California, 21 people attended what is now known as IETF 1. As we work on the day-to-day tasks needed to make the Internet work better, from time-to-time it is useful to consider our work on longer timescales. Here are my thoughts about the occasion: https://www.ietf.org/blog/2016/01/30-years-of-engineering-the-internet/ And happy birthday, IETF, on Saturday! What are your thoughts? Jari Arkko, IETF Chair
