It's working again this afternoon .... at least temporarily.
Just to be sure I was not going crazy yesterday: I made two CdC
screen-shots 30 minutes ago showing the successful download of a
USNO-B1.0 field from Vizier ('webviz' server), and the result screen
showing mag 20+ USNO-B stars. This was at declination +37 degrees.

So we can be sure that it is possible - at least sometimes - using
the 'webviz' server when it's available.
