We continuously monitor the status of our platform as well as external services we are using. If there
are any interruptions in service, a note will be posted here.

Update -
We previously announced a March 1, 2026 deadline to discontinue support for Transport Layer Security (TLS) 1.2 across all messaging-related services. We’d like to clarify that this deadline no longer applies.
While there is no longer a fixed timeline for the transition to TLS 1.3, we strongly encourage you to update your integrations to support TLS 1.3 as soon as possible. This applies to all connections to our messaging services and helps ensure secure and reliable communication.
Please note that, in some situations, traffic sent using TLS 1.2 or non-encrypted connections may be canceled to meet security or compliance requirements.
Why TLS 1.3? TLS 1.3 is a major step forward in both security and performance. It removes outdated cryptographic functions and simplifies the connection process, providing stronger protection for your data and more efficient communication. Moving to TLS 1.3 helps keep your services secure and running smoothly.
What you need to do We recommend reviewing your systems and updating any clients that still use TLS 1.2. Although there is no longer a set deadline, testing and ensuring full compatibility with TLS 1.3 as soon as possible can help prevent potential disruptions, particularly when connecting to destinations that require TLS 1.3.
Scheduled -
At CM.com, we are committed to providing secure and reliable services while adhering to the highest industry standards. As part of this commitment, we will be discontinuing support for Transport Layer Security (TLS) 1.2 on March 1, 2026, for all messaging-related services.
This change will impact all connections to our Business Messaging Gateway API and SMPP servers. After this date, any connection attempts made using TLS 1.2 will no longer be supported. To ensure uninterrupted service, we kindly request that you update your integrations to support TLS 1.3 before the deadline. Why TLS 1.3?
TLS 1.3 represents a significant advancement in security and performance. By removing outdated cryptographic functions and streamlining the connection handshake process, TLS 1.3 offers enhanced protection for your data and improved efficiency. This upgrade is essential to safeguard your communications and maintain the stability of your services.
What You Need to Do We strongly encourage all customers to review their systems and update any clients still using TLS 1.2. Please ensure your integrations are tested and fully compatible with TLS 1.3 well ahead of March 1, 2026, to avoid any disruptions.
On Januari 20th at 13:00 CET, we will perform maintenance on our Singapore Platform. This will impact all connections to SMPP 208 and all HTTP traffic towards gateway-sgp.cmtelecom.com. Active binds will be disconnected, and SMPP and HTTP will be unavailable until maintenance is completed.
Traffic towards http gateway sgp-gw.messaging.cm.com will be routed to our NL platform. We estimate this maintenance will take around five hours. Posted on

We experienced issues with our Triggered Campaign functionality between approximately 16:00 - 18:40 CET. During this time, triggered campaigns (campaigns triggered from CDP workflows and Triggered Campaigns API) failed to send.
Impact: All email triggers initiated during this timeframe were not delivered.
Current Status: We are actively investigating whether it is possible to recover the failed triggers and retroactively send the affected emails. We will provide an update as soon as we have more information. We sincerely apologize for any inconvenience this may have caused.

Summary: We experienced an issue with our campaign statistics processing system that affected the accuracy of delivery rate metrics in Campaign Insights. Timeframe: 10:00 CET January 7th - 10:00 CET January 8th Impact: Campaign statistics were not processed correctly during this period. Delivery rate statistics displayed in Campaign Insights were inaccurate All emails were sent out successfully and delivered as expected. No impact to actual email delivery or customer communications Root Cause: Events were processed through our queue system, but a misconfiguration caused messages to be processed incorrectly, resulting in inaccurate statistics. Resolution: The issue was resolved through a rollback and implementation of fixes to prevent similar misconfigurations in the future. Key Takeaway: While statistics reporting was affected, all triggered campaigns functioned normally and emails were delivered to recipients without interruption.
