    I've seen reports of this before. It is almost certainly some sort of temporary block. Sometimes they put these in place when there has been a DOS, denial of service, attack. For a scenario, imagine there's some bot network at unknown locations distributed around Europe sending vast quantities of data requests to servers in the US. Sometimes it's best to cut the chain out in the middle of the Atlantic --not literally, but in other words, you disconnect all traffic from some part of the globe for a while until the bots give up and stop the attack. If this lasts more than a couple of days, start complaining at both ends of the connection: your ISP and USNO. Also experiment with other related addresses. Can you reach any "navy.mil" addresses? Can you reach any ".mil" addresses?

    In any case, what can those of us with open connections to USNO servers get for you? Assuming you were interested in the "Astronomical Phenomena" publications which John Howard referenced at the start of this thread, I am including the three years that are available.
