Can't even ping? Chances are the network connection between
these two is down then, or someone put a firewall in between
or whatever.

Is your domain called ns1.y2knet.net? not y2knet.net? One
specifies the domain, not the nameserver as argument to ls.

But: better use dig(1) as nslookup is a horrible tool.

Is the primary still authoritative for the zone in question?
Does it have any errors in its logs on reload?

If you posted any more details, it would help

A check from my side:
	$ dig @ns1.y2knet.net y2knet.net soa

	; <<>> DiG 8.2 <<>> @ns1.y2knet.net y2knet.net soa=20
	; (1 server found)

indicates that your primary is not authoritative anymore for that zone.
Seems you have some syntax error in your zonefile. CHeck the logs !

Any details would.... (like real dig(1) output, logs, config files etc)
