Thank you for the encouraging idea that it could be a server problem. In the last six months, I have occasionally been able to download compete single maps as well as connected maps. In general, however, my success rate is poor (< 20%) compared to working from the Microsoft site.
The USGS site may have more traffic, a fact not obvious to the user, and that could account for incomplete data sets.
The National Map Viewer declared itself "not available or missing" during the evening of November 1. That is not surprising given the upset the storm may have caused. I shall keep trying,
