The Day Federal Data Went Dark: A Year of Monitoring and Action
January 31, 2025, is infamous as the day thousands of federal datasets and webpages went dark. While many of these resources have since been restored–often after being scrubbed of references to gender, DEI, and climate–they continue to face significant risks. In the webinar, we mark the one-year anniversary of this takedown to discuss the current state of federal data and recognize the immense amount of work that has been done to defend these public resources. Leaders from the data community will share insights on monitoring tools they have developed and the actions being taken to safeguard essential federal data.
