Internet Archive played crucial role in tracking shady CDC data removals

“These data are public and they are ours,” Rasmussen posted. “Deletion disobedience is one way to fight back.”

As Rasmussen sees it, deleting CDC data is “theft” from the public domain and archiving CDC data is simply taking “back what is ours.” But at the same time, her team is also taking steps to be sure the data they collected can be lawfully preserved. Because the CDC website has not been copied and hosted on a server, they expect their archive should be deemed lawful and remain online.

“I don’t put it past this administration to try to shut this stuff down by any means possible,” Rasmussen told Ars. “And we wanted to make sure there weren’t any sort of legal loopholes that would jeopardize anybody in the group, but also that would potentially jeopardize the data.”

It’s not clear if some data has already been lost. Seemingly the same user who uploaded the deleted datasets to IA posted on Reddit, clarifying that while the “full” archive “should contain all public datasets that were available” before “anything was scrubbed,” it likely only includes “most” of the “metadata and attachments.” So, researchers who download the data may still struggle to fill in some blanks.

To help researchers quickly access the missing data, anyone can help the IA seed the datasets, the Reddit user said in another post providing seeding and mirroring instructions. Currently dozens are seeding it for a couple hundred peers.

“Thank you to everyone who requested this important data, and particularly to those who have offered to mirror it,” the Reddit user wrote.

As Rasmussen works with her group to make their archive more user-friendly, her plan is to help as many researchers as possible fight back against data deletion by continuing to reference deleted data in their research. She suggested that effort—doing science that ignores Trump’s executive orders—is perhaps a more powerful way to resist and defend public health data than joining in loud protests, which many researchers based in the US (and perhaps relying on federal funding) may not be able to afford to do.

“Just by doing things and standing up for science with your actions, rather than your words, you can really make, I think, a big difference,” Rasmussen said.
