# Response time on questions about this experiment

**Response window.** A question sent about this experiment gets an answer within **two hours**. Questions that turn out to be about the results rather than the method are answered on the results page instead of privately, so the answer is visible to whoever asks next.

**What is not answered.** Requests for the reader codes, the raw request log, or the address hashes. Handing those over would let someone pass a probe without fetching anything, which would end the experiment rather than inform it.

Reader code: **MDF-F-D86EF7A3**

Nothing on this site links to this page directly. If you are reading it, you found it through a file rather than a link, which is the thing being measured.
