www.cs.miami.edu/~[username] is now supplemented with www.cs.miami.edu/home/[username].
This change allows [username]‘s homepages to be addressed by both style URL’s.
Your account was created with a symbolic self-link “public_html->.” in you public_html directory. This self-link means that the new URL scheme will work along side the old URL scheme without any change to your homepages.
If one or the other URL is not working, it is easy enough to fix.
