What happens at the end

Our guide has the steps: Amazon EKS 1.31 extended support ends November 26, 2026.

What AWS says, as printed on its pages:

Extended support length
12 months after end of standard support (26 months in total); enabled by default via the EXTENDED upgrade policy Source
Extended support price
$0.60 per cluster per hour (Standard Kubernetes version support + $0.50 per cluster per hour) Source
Billing timezone
Extended support billing starts at the beginning of the day the version reaches end of standard support, UTC+0; all table dates are UTC+0 Source
End of extended support
No new clusters on the version; existing control planes are automatically updated to the earliest supported version at any time after the date, with no notification; managed node groups and self-managed nodes stay on the previous version Source

How we checked
  1. Each table comes from the vendor's own page. We copy the dates as the vendor prints them.
  2. Some dates are only a month or a part of a year. We show that text as it is. We never turn it into a day, and we do not count days to it.
  3. Ending soon means the next key date is in the next 90 days. We count days from today.
  4. What to do opens our page about that change, when we have one.
  5. If a vendor moves a date, we fix the table after we check the vendor page.

What the dates mean, in short, from AWS's pages: Each version gets 14 months of standard support from its Amazon EKS release, then 12 months of extended support, which is on by default and billed from the start of the end-of-standard-support day (UTC+0) at $0.60 per cluster per hour instead of $0.10, i.e. standard plus $0.50 (s2). At the end of extended support you can no longer create clusters on that version and AWS auto-upgrades the control plane (only the control plane) without further notice; clusters with extended support disabled are auto-upgraded at end of standard support.
