In preparation for the upcoming iOS9 launch and the new security defaults, stronger connection ciphers will be applied to the Realtime Messaging HTTPS servers (Ignite and Corporate clusters). This update will allow better security but will affect some older platforms when the HTTPS protocol is used like Java 6, Android <2.3 and Windows XP. Higher than normal latencies will be experienced during the operation.
