+(June 22–26) at UN Headquarters in New York City, attending as a sponsored

+UN Open Source Week brings together governments, international organizations,
+maintainers, and the broader open source community to advance open source as
+infrastructure for the public good.
+
+## Join us at the Maintain-A-Thon on Monday, June 22
+
+Monday we'll be at the **Maintain-A-Thon** — a hands-on day bringing
+together open source maintainers, stewards, and policymakers to spotlight
+critical open source infrastructure. In the afternoon, we're co-leading a session on **AI tools in open source
+maintenance** (1:00 PM, breakout room to be announced that day so stay tuned).
+
+{{< admonition type="info" title="Session abstract" >}}
+What does it mean to maintain open-source software when the use of AI tools is
+rapidly reshaping all aspects of software development—from writing code,
+documentation, and infrastructure to submitting and reviewing contributions?
+
+Open-source workflows have long been built on human collaboration. The shift
+in the pace of software development and contributions, fueled by AI tool
+adoption, raises new questions about trust, quality, governance, and community
+norms. This session brings together maintainers and contributors across projects
+of all sizes to share real experiences, tensions, and emerging strategies: what
+is working, what is not, and where things are still being figured out—resulting
+in a crowd-sourced field report from the maintainers' perspective.
+{{< /admonition >}}
+
+The Maintain-A-Thon runs 10:00–18:00 in the breakout rooms at UN Headquarters.
+
+## Throughout the week
+
+We'll be on site for the full program, connecting with maintainers, OSPO
+partners, and others working on open source as public infrastructure —
+including themes like digital public infrastructure, OSPOs for Good, and
+community-led initiatives.
