Issue with loading data

Update timeline

1. investigating Apr 29, 2026, 04:03 AM UTC

   Decisions is currently experiencing issues with loading data via the Microsoft Graph service, resulting in a non-functional application for majority of users.

2. identified Apr 29, 2026, 08:11 AM UTC

   The issue has been identified, and mitigation is being rolled out. Service is starting to return for users.

3. monitoring Apr 29, 2026, 08:31 AM UTC

   All services are restored and operational. We continue to monitor the situation.

4. resolved Apr 29, 2026, 12:17 PM UTC

   On 29 April 2026, between 01:48 UTC and 08:10 UTC, the Decisions platform experienced intermittent service disruption caused by unexpected throttling of Microsoft Graph API requests. Customers saw failures and delays in features that depend on Microsoft Graph, including meeting and calendar operations, across multiple users and tenants. The root cause was a new platform-level throttling policy rolled out by Microsoft. As part of that rollout, a small number of applications, including Decisions, were incorrectly assigned to a highly restrictive throttling category, sharply reducing the API request limits available to our application. Engineering identified the cause at 03:20 UTC and escalated to Microsoft, who acknowledged the issue at 05:47 UTC. Mitigation was implemented and rolled out by 08:10 UTC, at which point all services were restored to normal operation. We are working with Microsoft to ensure such misclassification does not recur, expanding our monitoring to detect similar throttling anomalies earlier, and reinforcing existing safeguards to better handle platform degradation more gracefully.
