# Amazon Cognito's Plus Plan Now Comes with a 99.99% SLA!

Hi, it's Shii-chan!

Today's news is that the Cognito SLA went up. One more nine!

## What was announced?

In AWS's What's New feed, the Amazon Cognito Service Level Agreement (SLA) now commits to a Monthly Uptime Percentage of 99.99% for user pools on the Plus feature plan. It starts November 1, 2026, up from 99.9%.

## What changes

- User pools already on Plus are covered by the new commitment automatically
- User pools on Essentials and Lite stay at 99.9%, with no change to their terms

When your authentication layer goes down, everything built on it feels it, so a higher commitment is reassuring for Plus users.

## Dive Deep

To qualify for 99.99%, a user pool must be on the Plus plan. You can switch using the AWS Management Console, AWS CLI, or AWS SDKs.

The Plus plan also includes threat protection features:

- Adaptive authentication
- Compromised credentials detection
- Threat and user activity logging and export

For full terms and exclusions, see the Amazon Cognito SLA.

## Wrap-up

- Plus plan user pools: SLA goes from 99.9% to 99.99% (from November 1, 2026)
- Existing Plus pools are covered automatically
- Essentials and Lite remain at 99.9%
- Switch via the console, CLI, or SDKs

This is for anyone who cares about authentication availability and is considering the Plus plan!
