Is there a source for this? It looks like the document is hosted via the FCC's electronic comment filing system API, but I can't find a news source for this at all.
For whatever it's worth, I think comments hosted on that server have a different naming convention; usually it's /file/<comment id>/<original submitted file name>.extension

EDIT: Case and point, look at the format for comments in this proceeding: https://www.fcc.gov/ecfs/search/filings?proceedings_name=17-...
