AWS announces that all AWS Federal Information Processing Standard (FIPS) endpoints now only accept a minimum of Transport Layer Security (TLS) 1.2 connections

We are happy to announce that all AWS Federal Information Processing Standard (FIPS) endpoints have been updated to only accept a minimum of Transport Layer Security (TLS) 1.2 connections. This update ensures that our customers who run regulated workloads can meet FedRAMP compliance requirements that mandate a minimum of TLS 1.2 encryption for data in transit. Attempts to connect to AWS FIPS endpoints using TLS 1.0 or TLS 1.1 will result in an HTTP response 503 Service Unavailable error.
