Astound user webspace
But no worries; a bit of poking around with likely hostnames identifies the following:
FTP upload: ftp to users.ca.astound.net (or ftp.ca.astound.net; same IP address); login with your email username/password; put files in the public_html directory.
Web server: http://users.ca.astound.net/username. Their web server serves index.html or index.htm as the default page for a directory.
Minnesota Astound customers replace ca with mn as usual.
Oh, and while we're at it: they don't tell their customers about NNTP service either, but it exists. Newsserver at nntp.astound.net.
