Hi John,
I am operationally reading GFS 0.5deg data from the NOMADS-HD server via
DODS and the Java/NetCDF library. I did not change anything in my code
during the last couple of months, but recently (for instance the last 20
hours) there have been some errors reading data from there (see the
protocol below). I think I remember that there was a similar problem last
fall, and the reason was a change in some security or firewall setting on
NOMADS, just concerning this protocol. Do you know what the reason for the
messages can be or who might be responsible? Thanks, Gerald
