DNS errors

My DNS seems to work between my master and slave and my local workstation.

But when I go to a remote website viewer, I get these errors:

DNS Records
Host www.buyorangecat.com not found: 2(SERVFAIL)
A Records
Host www.buyorangecat.com not found: 2(SERVFAIL)
CNAME Records
Host www.buyorangecat.com not found: 2(SERVFAIL)
MX Records
Host www.buyorangecat.com not found: 2(SERVFAIL)
TXT Records
Host www.buyorangecat.com not found: 2(SERVFAIL)
SOA Records
Host www.buyorangecat.com not found: 2(SERVFAIL)

When I perform a dig on my name server, it looks good to me:

dig @45.33.50.180 twocanes.us. SOA
; <<>> DiG 9.11.4-3ubuntu5-Ubuntu <<>> @45.33.50.180 twocanes.us. SOA

and

If anybody can see an error, I'd love to know what it is. ;-)

Hello,

The nameservers that are authoritative for that domain aren't resolving:

$ nslookup NS1.TWOCANES.US
;; Got SERVFAIL reply from 8.8.8.8, trying next server
Server:        1.1.1.1
Address:    1.1.1.1#53

** server can't find NS1.TWOCANES.US: SERVFAIL

Hope that helps!

I kinda surmised that, but why are the not resolving?

Here's my named.conf.options file (bind9):

options {
directory "/etc/bind";

// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk.  See http://www.kb.cert.org/vuls/id/800113

// If your ISP provided one or more IP addresses for stable 
// nameservers, you probably want to use them as forwarders.  
// Uncomment the following block, and insert the addresses replacing 
// the all-0's placeholder.

 forwarders {
    8.8.8.8;
    50.116.53.5;
    50.116.58.5;
    50.116.61.5;
    50.116.62.5;
    66.175.211.5;
    8.8.4.4;
 };
//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys.  See https://www.isc.org/bind-keys
//========================================================================
dnssec-validation auto;
//listen-on-v6 { any; };

};

I'm using the Linode DNS resolvers listed on the manager page for my nameserver, ns1.twocanes.us
