AWS Elastic Load Balancing: Seeing extremely long initial connection time

Question

For a couple of days, we often see an extremely long initial connection time (15s - 1.3 minutes) to our ELBs when making any request via ssl. Oddly, I was only able to obse

Answer 1

For me the issue was that I had an unused "Availability Zone" in my Classic Load Balancer. Once I removed the unhealthy and unused Availability Zone the consistent 20 or 21 second delay in "Initial Connection" dropped to under 50ms.

Note: You may need to give it time to update. I had my DNS TTL set to 60 seconds so I would see the fix within a minute of removing the unused Availability Zone.
