that's not really a way to determine the reason why it doesn't work for
you.

let's see closer:

 > dig man.NetBSD.org
 ...
 ;; ANSWER SECTION:
 man.NetBSD.org.         23h59m28s IN CNAME  web-a.us.gw.com.

 ;; AUTHORITY SECTION:
 gw.com.                 14m28s IN SOA   seven.gw.com. kim.gw.com. (
 ...

as you can see, man.netbsd.org is a CNAME record for web-a.us.gw.com,
that's what your (and my) dns server has in its cache.  but
authoritative nameservers for gw.com don't know about web-a.us.gw.com
anymore.

now let's ask the authoritative nameserver for NetBSD.org domain:

 > dig @ns.NetBSD.org man.NetBSD.org
 ...
 ;; ANSWER SECTION:
 man.NetBSD.org.         86400   IN      CNAME   web-a.fi.gw.com.
 web-a.fi.gw.com.        522     IN      A       213.28.202.226

so as you can see from inspecting the ip address ranges the machine in
question was moved from USA to Finland and its A record changed.
man.NetBSD.org CNAME record was updated but it didn't reach your
nameserver, since it has the previous entry in cache and it didn't
expire, yet.
