I am having issues with changing the instance type of my AWS servers that are hosted through Amazon/Turnkey. I've been experimenting with instance types for a particular application... and have a few times changed it from small to medium or visa versa through the Amazon AWS control panel.
My problem is that when I do this, the IP of the AWS server changes, and the Dynamic DNS gets knocked out. Further confusing the matter is that I've figured out that it's only my local DNS that's experiencing this issue. If I try using a proxy site (hidemyass.com is my go-to), the Dynamic DNS URL works fine.
I'm using Windows 7, and no matter how many times I run "ipconfig /flushdns" nothing changes. All computers in my office are currently resolving my Dynamic URL to the wrong IP.
I tried logging into one of my other Amazon AWS servers, and when I ping the dynamic URL it DOES resolve to the right domain.
This has become a problem, because one of our customers experienced a day outage of service while we waited for DNS settings to propigate after I changed a server instance type on a Sunday evening.
What can I do to get the right DNS settings on my local computer, and more importantly... what can I do to ensure that if/when I need to change an instance type again that the DNS changes propigate as quickly as possible.
