There was much social media speculation over the weekend that this was a 
DNS issue, but it seems a lot of NIH online infrastructure was taken 
down without too much heed for the side-effects.

I suspect that Saturday's news:

	https://www.npr.org/sections/shots-health-news/2025/03/01/g-s1-51514/francis-collins-nih-national-institutes-health-resigns

just before all this started is not unrelated, and the outages' root 
cause are fundamentally a layer-9 rather than DNS issue
