Hey everyone! I'm trying to understand the connection between the implementation of private subnets and the upcoming end of Default Outbound connectivity slated for September 2025. Does this mean that all subnets will behave like private subnets after that date? I'm a bit confused and would love some clarification on this!

So here's the deal: Before September, your VMs have a default outbound route, even if they're in private subnets. But once September hits, you'll need to manage that outbound route yourself, or your VMs won't connect to the internet at all.
Yeah, you got it! After September 2025, any new subnets will pretty much operate as private subnets. Switching to a private subnet now can help you prepare for that change and see how it might affect you.
ok, got it thanks !
Sorry, but there's a bit off in that explanation.
1. Private subnets actually disable the default outbound route for all VMs, even if they were just provisioned.
2. Post-September, any new VMs added won't have a default outbound route, even if they are in non-private subnets.
3. VMs that were set up prior to the change will keep their default outbound access unless they are in a private subnet.
