Yes, it is safe, the link leads to pharo contribution CI server and in particular to the build of the catalog of pharo configurations.

If you wand to get familiar with pillar, here is the GitHub group: https://github.com/pillar-markup
And here is a repo with documentation: https://github.com/pillar-markup/pillar-documentation

Hello

Where is the main Pillar web site

Google for

      pillar Pharo

gives as first hit

https://ci.inria.fr/pharo-contribution/job/PharoProjectCatalog/HTML_Report/Pillar.html

which is an untrusted connection.
Is it safe to continue?
