Dear Valued Customer,
As part of our ongoing commitment to platform stability and performance, we will be performing a phased infrastructure upgrade to the CHI Backend starting April 18, 2026.
What is changing?
We are migrating our backend processing environment to a container-based architecture. This Phase I deployment focuses on runtime optimization and lays the groundwork for our upcoming upgrade to Python 3.12.
Note: There are no changes to the current UI/frontend, and your user experience will remain the same.
Maintenance Schedule:
The migration will occur in regional windows to ensure minimal impact on Cloud Helix Integrations(CHI) within the following regions:
-
EU Regions: April 18 – April 19 (starting 4:30 a.m. UTC)
-
AP Regions: April 19 (starting 4:30 a.m. UTC)
- US Regions: April 25 – April 26 (Windows at 4:30 a.m. and 12:30 p.m. UTC)
What to expect:
-
Service Availability: While we aim for a seamless transition, there is a possibility of brief service interruptions lasting between 60 to 90 minutes during the maintenance window.
-
Data Integrity: Please be assured that no data or events will be lost during this period. All processes will resume automatically once the update is complete.
- Action Required: No action is required on your part.
Our Engineering and SRE teams will be monitoring the transition closely.
