yeah, it's not technically a sunset period if they haven't announced the service will be ending. but they've been sending some pretty strong clues - afaik you haven't been able to create new EC2 classic instances for many years now.

From Jeff's blog post:

> All AWS accounts created after December 4, 2013 are already VPC-only, unless EC2-Classic was enabled as a result of a support request.

There were announcements made at the time, but I don't remember if they explicitly called it a deprecated product at the time (hence why I hedged my wording in GP comment).

The writing has been on the wall for quite a while. I got us off our last classics this year due to the october date they had been saying before.
