comment For sudo su - to retain SUDO_* environment variables?
Adding this line: Defaults env_keep += "SUDO_USER SUDO_UID SUDO_COMMAND" does resolve the issue for sudo -i ... but doesn't seem to help for sudo su -; I'm going to guess that nothing short of a patch to the su command would solve that latter issue.

comment For sudo su - to retain SUDO_* environment variables?
I hope it's clear that we're not concerned about hostile users getting access to the sudo authorized commands in this environment. The use of sudo here is merely intended to minimize the time that our operations staff are exposed the root prompt where any finger fumbling can have dire consequences. The idea is to have convenient access to a fully initialized root shell while also allowing relatively convenient access to various remote authenticated services under various ops team member names.

comment How do I Delegate a subdomain to Route53
MadHatter: I do usually redact IP and domain information from most questions. But this involved public facing DNS ... so the information is public anyway.

comment How to enable traceroute in linux machine
Actually the old MS Windows TRACERT.EXE does use UDP rather than ICMP and the Linux version offers options to use TCP (-T) or UDP (-U) instead of the default (ICMP). From the traceroute man page on a Debian system: "We don't want the destination host to process the UDP probe packets, so the destination port is set to an unlikely value (you can change it with the -p flag). There is no such a problem for ICMP or TCP tracerouting (for TCP we use half-open technique, which prevents our probes to be seen by applications on the destination host)." MacOS X seems to default to UDP as well.
