AWS’s new hidden `ExtendedSupportYr1_Yr2` charge for older versions of RDS and Elasticache

AWS’s new hidden ExtendedSupportYr1_Yr2 charge for older versions of RDS and Elasticache
AWS just snuck in a new hidden charge that adds up quickly.
In the case I found recently, the costs were over a hundred dollars PER DAY (Not per month)
As of February 1st, 2026, you might see a line item that includes the text ExtendedSupportYr1_Yr2 something like USW1-ExtendedSupportYr1_Yr2-NodeUsage:cache.r6g.4xlarge snuck in there.
From what I observed, that new additional cost was over 50% of what the hourly cost for the instance was, effectively jacking up the price of the instance.
Now it sounds like I am hating, but I kind of understand why they did this.
Let's examine their other options:
Shut down your instance.
Obviously, this would disrupt your service, so not an ideal option.
Auto update your cluster:
This could cause some version issues that introduce breaking changes, so again not ideal.
Charge more until you fix it:
Not ideal, but if you're not checking your notifications and/or not taking action to fix it, what else are they to do?
Maintaining software that is out of date with the SLAs/uptimes AWS boats is not easy, and it sure is not cheap.
Recommended Action:
Double-check your AWS bill to make sure you're not paying this extra tax on older RDS/Elasticache versions.
