Edited GC's external DNS server with new DNS delegation records:

commons.gc.cuny.edu.    IN      NS      ns-248.awsdns-31.com.
                        IN      NS      ns-1445.awsdns-52.org.
                        IN      NS      ns-1635.awsdns-12.co.uk.
                        IN      NS      ns-791.awsdns-34.net.
                        IN      NS      ns-248.awsdns-31.com.

...and it worked:

[apitanga@GZZQJQ1 ~]$ dig @pennstation commons.gc.cuny.edu

Edited GC's internal DNS server in the same way, and it also worked ok:

[apitanga@GZZQJQ1 ~]$ dig commons.gc.cuny.edu

This is basically done. I'll keep the issue open for a second though to let things run with the new configuration for a little while before considering it resolved.

Later I'll create a record on Route 53 for a single sub-sub-domain (say, if.commons.gc.cuny.edu) and point that to Baruch to simulate a fail-over.

Looks like it's running alright for a while, so I'm calling this one resolved.
