Network Solutions DNS Servers hacked already?

I was just hipped to the fact that two DNS servers apparently operated by Network Solutions aren’t returning valid results for some domains, notably www.google.com:

[pvenezia@mba ~]$ nslookup www.google.com 

Server:         172.16.32.10
Address:        172.16.32.10#53

Non-authoritative answer:

www.google.com  canonical name = www.l.google.com.
Name:   www.l.google.com

Address: 64.233.169.147
Name:   www.l.google.com

Address: 64.233.169.99
Name:   www.l.google.com

Address: 64.233.169.103
Name:   www.l.google.com

Address: 64.233.169.104

[pvenezia@mba ~]$ nslookup www.google.com 205.178.190.32

Server:         205.178.190.32
Address:        205.178.190.32#53

Name:   www.google.com

Address: 205.178.145.65

[pvenezia@mba ~]$ whois 205.178.190.32

Non-authoritative answer:

32.190.178.205.in-addr.arpa     name = ns63.worldnic.com.

Authoritative answers can be found from:

190.178.205.in-addr.arpa        nameserver = ns1.netsol.com.
190.178.205.in-addr.arpa        nameserver = ns2.netsol.com.

190.178.205.in-addr.arpa        nameserver = ns3.netsol.com.
