It's not in any sort of format to do this kind of analysis unfortunately. I'm also missing some data b/c I throw away certain kinds of datasets that are not useful for me. I can probably write some scripts to diff my archives with the current data.gov and see what's missing, but it won't be "complete". But it might still be useful...

I did however just write a Python script to pull data.gov from archive.org and check the dataset count on the front page for all of 2024, here are the results:

As you can see, there were multiple drops on the order of ~10,000 during 2024. So it's not that unusual. There could be something bad going on right now, but just from the numbers I can't conclude that yet.

(Specifically it takes the first snapshot of every Wednesday of 2024).

If I get around to re-formatting my archives this week, I'll follow up on HN :).
