[galaxy-user] Problem with ftp server?

I successfully uploaded files to the main Galaxy server this morning using ftp. However, any attempts to upload files since around noon have failed. I get a 'Could not connect to server' error when trying to connect to main.g2.bx.psu.edu uisng FileZilla. Any suggestions? Thank you. Katrien -- Katrien M.
