       Listed on the next page are several important packages located at
-      ftp.gnu.org.  That site is the canonical location of the
-      subject packages but has been affected by a long term
-      distributed denial of services (DDOS) attack.  See
+      <uri>ftpmirror.gnu.org</uri>.  The canonical location of the
