Description
Enabled "cloud" DNS via Amazon AWS to allow fail-over to secondary data center at Baruch College.
Updated by local admin over 12 years ago
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 ; <<>> DiG 9.7.3-P3-RedHat-9.7.3-8.P3.el6_2.2 <<>> @pennstation commons.gc.cuny.edu ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 17216 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 2 ;; QUESTION SECTION: ;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 ; <<>> DiG 9.7.3-P3-RedHat-9.7.3-8.P3.el6_2.2 <<>> commons.gc.cuny.edu ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4149 ;; flags: qr aa; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 0 ;; QUESTION SECTION: ;commons.gc.cuny.edu.

- % Done changed from 0 to 100
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.

Quoting myself ;-)

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

Created record for if.commons.gc.cuny.edu that points it to Baruch and that works. We're good to go DNS-wise.
