IBM Cloud will stop supporting TLS 1.0 and 1.1 on api.softlayer.com and api.service.softlayer.com
On March 1, 2018 at 0900 UTC (0300 CDT) IBM Cloud Infrastructure will stop supporting TLS 1.0 and 1.1 encryption on api.softlayer.com and api.service.softlayer.com; these API endpoints will only support callers using TLS 1.2 encryption levels or higher.
On March 1, 2018 at 0900 UTC (0300 CDT) TLS 1.0 and TLS 1.1 will no longer be supported and TLS 1.2+ is required.
Any users with code or services that reference the softlayer.com API endpoints for IBM Cloud Infrastructure services with encryption levels older than TLS 1.2.
Confirming and Testing Upgrades to TLS 1.2 or Higher The enhanced security configuration is currently enforced on alternate endpoints. You can test your services against them now to ensure there will be no disruption once the primary endpoints receive the updated configuration:
These alternative endpoints only use encryption levels TLS 1.2 or higher. Successfully testing your code and services against these alternative endpoints means your code and services will work properly on the transition date. These alternative endpoints will only be available until the transition date.
If you make no change and your code or services do not support encryption levels TLS 1.2 or higher, you will start to experience connection errors on the transition date. These errors may appear as “transport errors” and contain messages like SSLV3_ALERT_HANDSHAKE_FAILURE. Your code and services will no longer function until you upgrade it to support TLS 1.2 or higher.
If My Code Starts Failing Do I Have Any Temporary Recourse? If you start to experience connection errors on the transition date, the best course of action is to upgrade your code or services to support TLS 1.2 or higher. If you cannot do that immediately, there will be alternative endpoints provided temporarily to allow you to upgrade your code or services:
These endpoints will become available on the transition date, and will continue to support TLS 1.0 and 1.1. You can change failing code or services to use these endpoints temporarily while you upgrade your systems to support TLS 1.2 or higher. These endpoints will only be available until March 30, 2018 to allow you to make this transition. You must upgrade all your systems and start using the standard API endpoints by March 1, 2018.
This is part of IBM’s commitment to offering a cloud that is secure to the core and in alignment with industry best practices for security and data privacy.
