Andrei,
Yes, wget 1.9.1 consideres failure to connect as a fatal error and abandoned to re-try attempts. I have submitted several times a patch for
fixing this and similar problems. Presumably, it will be inlcuded in
the future wget 1.11 . If yoy need the fix now, you can find it
the patch against wget-1.10-alpha1 in http://software.lpetrov.net/wget-1.10-persistent.patch
or alternatively an entire tarball in http://software.lpetrov.net/wget-pet/
Good luck
