Blocked Page

Your organization has blocked access to this page or website.

on the PPA box, this is what it showed me (meanwhile it was attempting to connect to incoming.telemetry.mozilla.org). another symptom of displaying respect for enterprise policies but in fact ignoring them. (as i had mentioned, on this box all of the settings look locked down as they should be, but it’s still attempting to send telemetry.)

It exists, it’s called a robots.txt file that the developers can put into place, and then bots like the webarchive crawler will ignore the content.

the internet archive doesn’t respect robots.txt:

Over time we have observed that the robots.txt files that are geared toward search engine crawlers do not necessarily serve our archival purposes.

the only way to stay out of the internet archive is to follow the process they created and hope they agree to remove you. or firewall them.
