Wonderful. Love this. The whack-a-mole with corporate firewalls gets annoying quickly.

If you run into other servers I've missed, please let us know. I did run a grep check over our entire code base, but:

1. I might have missed some.
2. There might be services being accessed through a dependency that I'm not aware of.

@cscheid did you keep this page hidden on purpose right now ?
I is available at https://prerelease.quarto.org/docs/advanced/html/external-sources.html

but it is not discoverable in Advanced menu or somewhere else.

I think we could add to Advanced section

quarto-web/_quarto.yml

Lines 427 to 437 in 75dbc53

	- section: "Advanced"
	contents:
	- docs/authoring/includes.qmd
	- docs/authoring/variables.qmd
	- docs/output-formats/page-layout.qmd
	- docs/authoring/language.qmd
	- docs/authoring/conditional.qmd
	- docs/extensions/nbfilter.qmd
	- section: "Jupyter"
	contents:
	- docs/advanced/jupyter/kernel-execution.qmd

Or mayb add a FAQ item and link to the page from there ?
https://prerelease.quarto.org/docs/faq/

Before doing that, I wanted to ask if this was not yet exposed on purpose.

[cscheid]

No good reason on my part. I just wanted to make sure I had documented the issue without having to solve the organization problem.
