I have a user in Australia who cannot access our site. Our site sits behind an AWS ELB which seems to work fine. While troubleshooting his machine remotely I can see that ELB issues two IP addresses - one of which he always gets a time out.
So every request to our site gets one of the two IP addresses - 50.x.x.x or 184.x.x.x. If he gets the 50.x.x.x the site doesn't work.
Curious, I decided to verify this by checking a separate company who I know uses ELB. The same problem happens. Two IP's are issued randomly between requests. The site works only on one of them.
How in the heck can I fix this? What are my options? I figure it would be easier to ask here vs. AWS.
