ietf.org has physically diverse secondaries so it strikes me as unlikely
that this problem is outside sprint

ietf.org.		86400	IN	NS	ns0.amsl.com.
ietf.org.		86400	IN	NS	ns1.ams1.afilias-nst.info.
ietf.org.		86400	IN	NS	ns1.mia1.afilias-nst.info.
ietf.org.		86400	IN	NS	ns1.sea1.afilias-nst.info.
ietf.org.		86400	IN	NS	ns1.hkg1.afilias-nst.info.
ietf.org.		86400	IN	NS	ns1.yyz1.afilias-nst.info.
