Random bit of information related to this bug.
On EC2:
$ host instance-data.
Host instance-data. not found: 3(NXDOMAIN)
$ host instance-data
instance-data.ec2.internal has address 169.254.169.254
So, the change we put in here would prevent this from working in EC2. Note, though, that the search path includes the IP, so it still works.
