## Tasks

* [x] code to search for broken links in  web pages
* [x] run gn2 on CI as a background task to search for broken links



### Notes



the bug above no longer exists.

gn2 CI runs on the background after for any push
raises an error if any broken link is found
On gn2 web pages all missing links that are found
are underlined and highlighted with red for later fix


### Update

we no longer use github CI this should be moved the new gn2 CI

### Resolution

This was added to Mechanical Rob here:

=> https://github.com/genenetwork/genenetwork2/pull/555

Making Mechanical Rob should it fail is an entirely different issue.
