Dear Valued Customer,
As part of our ongoing commitment to platform stability and performance, we will be performing a phase two infrastructure upgrade to the Cloud Helix Integrations (CHI) backend starting July 25, 2026.
What is changing?
We are migrating our backend processing environment to a container-based architecture. This Phase II deployment focuses on runtime optimization, upgrading the Python version to 3.14, and introducing SQS for event handling.
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). Please note that the schedule below is based on your specific CHI region which may differ from your Helix instance region:
| Region | Maintenance Window |
|---|---|
| EU regions | July 25–26 (starting 4:30 a.m. UTC) |
| AP regions | July 26 (starting 4:30 a.m. UTC) |
| US regions (West-1 and East-2) | August 1 (starting 4:30 a.m. UTC) |
| Canada regions | August 1 (starting 4:30 a.m. UTC) |
| Africa regions | August 1 (starting 12:30 p.m. UTC) |
| Middle East regions | August 1 (starting 12:30 p.m. UTC) |
| South America regions | August 1 (starting 12:30 p.m. UTC) |
| US region (East-1) | August 1 (starting 12:30 p.m. UTC) |
| US region (West-2) | August 2 (starting 4:30 a.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
