Multi Region Cognito Support

Unfortunately, multi-region replication is not currently supported for Amazon Cognito user pools. However, here are a few insights on the possibilities of it being added in the future:

Multi-region replication is a popularly requested feature for Cognito based on feedback in AWS forums and the most upvoted Cognito idea on the AWS feature request site. This indicates it's something AWS is likely considering.
In late 2021, AWS announced multi-region replication for other databases like Aurora and DocumentDB. This shows a precedent for adding cross-region capabilities to other managed services.
However, AWS has not made any official announcement indicating if/when Cognito will receive multi-region support. The Cognito roadmap is not public.
A few AWS developers have commented that multi-region for Cognito poses some complex technical challenges related to syncing user data, tokens, etc. This means significant engineering work would be required.

Overall, multi-region replication for Cognito user pools seems highly likely to come eventually based on customer demand. But the timing is uncertain. I would keep an eye out for relevant announcements from AWS, perhaps in late 2023. For now, if cross-region redundancy is absolutely critical, you may need to consider workarounds like replicating just the Cognito user directory data. Hope this helps provide some insights on the possibilities! Let me know if you have any other questions.
