On 18 June 2026, following a large load event, certain tasks within client journeys temporarily slowed progression across a number of production environments.

The investigation identified the root cause and the source of the additional processing was identified and stopped. Normal task processing resumed and all affected journeys progressed without any manual intervention or loss of data.

The following services were impacted during this incident:

There was no impact on the accuracy or integrity of work completed prior to the incident. No data loss occurred.

The impact was contained to the client journey processing (tasks) area of the platform; all other areas of the Fenergo application continued to operate normally throughout the incident.

Recovery was completed across all impacted environments on the same day.

The root cause of this incident was an unusually high volume of processing activity temporarily consumed shared system capacity that is also used for standard task processing.

The activity triggered a much larger volume of downstream system processing than is typical. This additional processing temporarily used up shared system resources, which in turn slowed the normal processing that drives task progression for other journeys.

An existing system behaviour meant that certain bulk actions could generate a larger amount of downstream processing than expected. Work to address this behaviour was already underway prior to this incident.

The final corrective deployment resolved the issue at its source. All affected tasks were subsequently reprocessed, and impacted client journeys were unblocked on the same day.

Fenergo has identified the following corrective actions to prevent recurrence:

Fenergo takes the reliability of its platform and the continuity of our clients' operations seriously. We are committed to delivering the corrective actions outlined above and to embedding the lessons learned from this incident into our engineering and deployment practices.

We apologise for the disruption caused and thank our clients for their patience and continued partnership with our support teams throughout the recovery process.

System has recovered since 16.30. Full RCA will be published in coming days

Fenergo are monitoring and observing system is recovered. We will continue to monitor and will provide RCA in coming days. All journeys will processed including those affected

Fenergo monitoring has alerted us to an issue with the Tenants on EMEA1
This is resulting in service degradation and journeys becoming stuck on tenants within that region
