Attendees checked in: 143 (38 First Time attendees)

DNS-OARC held a two-day hybrid workshop this February in Atlanta following NANOG 87 . It featured presentations and networking opportunities to discuss the latest trends, issues and challenges in DNS operations and analysis. It provided a valuable platform for participants to exchange ideas, share best practices, and collaborate on ways to improve the security, stability, and resiliency of DNS.

We were happy to see an increase in our attendance with both virtual and remote attendees around the world during our last two workshops. We had a total of 143 attendees at OARC 40 and 108 at OARC 39, putting us much closer to pre-COVID attendance numbers but also showing that we are getting approximately 50% remote attendance rather than in-person.

Over the course of both days — during the coffee breaks and lunch, DNS-OARC Membership Coordinator, Steve Sullivan demonstrated the OARC Portal to those who were interested in learning how to better utilize the tool.

The day ended with the OARC 40 Social Event at the Metro Diner and Bar Atlanta . This was a fantastic evening that was enjoyed by delegates and OARC staff, with drinks, snacks and and a DJ with karaoke entertainment over a period of 2.5 hours.

Keith Mitchell announced that OARC is now running a Mastodon instance to provide federated social media for the DNS Community. The instance is now open for OARC Members and will be open to the wider community in the very near future.

Overall, the OARC 40 workshop was a great success, bringing together a diverse range of DNS professionals and experts to discuss the latest developments and challenges in the field. With DNS playing an increasingly critical role in our digital lives, events like OARC 40 are essential to ensuring the Internet's continued growth and success. We look forward to seeing everyone at OARC 41 this fall.
