May 24, 2023 (10pm PDT)/June 9, 2023 May 25, 2023 (5:00am GMT) we will be performing networking updates for Production, beginning at 10:00pm Pacific.
This update will remove support for CBC ciphers and add support for TLS v1.3. ECDHE GCM are preferred ciphers to be used at this time. This change will only impact API connections and integrations.
