[Difx-users] GSFC website down

[Walter Brisken]

Hi Chris,

I'm hoping the FTP solution can be a workable stopgap for the next month 
or so, afterwhich we move to a more permanent solution.  In the meantime 
I'd rather not double the effort on my part or change things that folks 
may have gotten used to.  In the next 2 weeks I will work with folks to 
figure something out.

It could be that for many / most of us, migration to the USNO service, 
which is online and offers data products via ftp or http, could work. 
To see what is offered, go to : http://maia.usno.navy.mil/ .

Cheers,

Walter
