Recent federal actions have disrupted access to key datasets, raising concerns about the long-term availability of some essential public data sources. In response, Metro has launched an internal initiative to track changes, assess impacts, and share knowledge across departments. This lightning talk will outline our approach, which included the creation of a Public Data Watch SharePoint site and Teams channel to facilitate collaboration. We will share key takeaways, challenges, and resources, including archives and data preservation efforts. Attendees will gain practical strategies and access to a one-pager with links to helpful resources.
