I have a Facebook comment and I would like to get the user ID of the author of the comment. I am able to get this information when the comment is posted on the page that I own with this query:
https://graph.facebook.com/v2.11/comment_id?fields=from&access_token=access_token
However, the same does not work when I am accessing a comment that is not posted on my own page, the from field is never returned. Is it possible to get the author of a comment that is posted on a different page?

No, that information is not available to you any more.
https://developers.facebook.com/docs/graph-api/changelog/version2.11#gapi-90-pages:
/page/* — User information will not be included in GET responses for any objects owned by (on) a Page unless the request is made with a Page access token. This affects all nodes and edges that return data for objects owned by a Page.
from field still not returning anything. And then I thought, if it's not working, why there is still in the docs. The endpoint used comment_id?fields=from&access_token=page_access_token. Graph API v2.12. I've just tested it in the explorer.
If you are using a development account you cannot get the from user details of a user who comments on your posts. You can however create test users from your developer account, login with the test account, comment and retrieve their from details.
