The Matrix Public Archive is on hold

I expect the permalinks that I had shared previously over https://archive.matrix.org/ to continue to work. Instead, I am greeted with the following error message:

> We are reviewing the Matrix Public Archive to ensure that it doesn't break privacy expectations and have taken it down as a temporary measure while we conduct the investigation.

Start by reviewing the issue report and the current response at https://archive.matrix.org/. No source file, test, or entry point is identified in the payload. Done would require establishing whether the archive can safely support the previously shared permalinks and defining the required behavior after the privacy investigation.
