public.asimov.net failed?

["Bryan Parkoff" <nospam@nospam.com>]

Hello,

    I tried to access to public.asimov.net, but I was unable to go through. 
Sometimes, it works, but sometimes, it does not.  It may be the network 
problem inside their servers.  I used mirror to three different servers, but 
it failed.

ftp://ftp1.us.il.apple.asimov.net/pub/apple_II
ftp://ftp1.us.tx.apple.asimov.net/pub/apple_II
ftp://ftp1.au.apple.asimov.net/pub/apple2
http://ftp1.au.apple.asimov.net/pub/apple2

    Mirror above does not work.  Do you have idea what is causing?
