Meaning of roos in a Canvas URL?

Good morning, in reviewing the tracking of page activity of a Canvas user, I have come across URLS using the notation roos. A partial example follows:

https://xxxxxxx.instructure.com/courses/xxxx/pages/roos/.....

Does anyone know what the roos is about?

It seems to be associated with the measurement of Internet connectivity.

Thank you so much for any insights you may have

I take it that this appears more than once. Are the urls that follow the roos valid?

I'm not familiar with "roos", but having anything between /pages/ and the url for the page would break the page router in Canvas. It would not take you anywhere.

roos does not appear anywhere in the Canvas open source anywhere.

I've seen web log entries that shouldn't be there. Any webserver routinely gets requests for pages with known vulnerabilities, even though they don't appear on the server. Someone is probing to find an exploit.

If this is tied to a student (and not just a random page from the weblogs), is there other evidence that the student's account has been hacked? Perhaps the student was trying to automate something and had a bug in their program? Maybe the student was doing something else and randomly inserted roos in there (my laptop routinely jumps me to a place I wasn't at and then I finish typing before I realize it, although getting an extra slash in there would be difficult to explain).

Is it possible that the bad link is contained within a page or assignment within Canvas? Can you identify where the student was before that link showed up and then see if that page has a bad link on it?

What was the http status code for those requests?
