Isn't this falls outside amazon's responsibly area?
Atleast the documentation I read and a few aws promotional talks I attended seems to suggest the contrary.
Or I have understood completely wrong and amazon is now also providing managed IT services?
But when you pay AWS so much they are pretty beholden to your requests and can wind up becoming a lot like an MSP. I've spent countless hours with those poor guys waiting on a traceroute failure or for mtr or sat to give some anomalous event that everyone suspects is something wrong in AWS when I've insisted AWS is almost never at fault because our incompetence is almost certainly the problem.
The AWS support team's worst engineer is probably at least in the top 25% of our support engineers I'd argue so I'm sure if my customer had the option they'd want to pay to have them troubleshoot our own internal networks but that's what my team is for I guess.
