Clients may be unable to contact us at this time.

Feb <var data-var='date'>26</var>, <var data-var='time'>15:00</var> UTC Resolved - Description: Between 15:00 and 18:08 UTC on February 26, 2026, one database node in our EU production cluster experienced network throttling, resulting in increased query latency. This manifested as general interface sluggishness and intermittent API response delays. Root Cause: A spike in traffic triggered AWS network throttling on the affected database instance, leading to degraded performance. Resolution: Traffic was redirected to another instance, restoring normal operation. Next Steps: We are strengthening network monitoring, reviewing instance sizing, and working with the platform team to implement additional traffic control measures to prevent recurrence.

EU Production Database Performance Incident

Feb <var data-var='date'>20</var>, <var data-var='time'>12:00</var> UTC Resolved - Between 20.02 (12:00 UTC) and 23.02 (18:00 UTC), during a scheduled aggregation tables migration, a configuration inconsistency caused partial data to not be fully reflected in the production aggregation layer. This affected certain rules relying on aggregate expressions for a limited period. Core monitoring and transaction processing were not impacted, and no data loss occurred. The issue has been resolved and aggregation data fully reconciled. Additional validation and automation controls have been implemented to prevent recurrence. As a precaution, we will automatically rescore all transactions evaluated by aggregate-based rules during the affected period. If you have any questions or require assistance, please contact our Support team.
