Incident Report

Summary AI Generated

A 60-hour infrastructure issue in Salesforce's US-East-1 region caused performance degradation across multiple cloud services, with customers experiencing slow performance, intermittent 500 errors, dashboard loading failures, and database accessibility issues affecting Heroku, MuleSoft, Marketing Cloud Intelligence, and Marketing Cloud Personalization. The incident was caused by a third-party infrastructure provider problem in a single availability zone, requiring traffic redirection and service migration to healthy infrastructure. Most services were restored by redirecting workloads to unaffected zones, with MuleSoft recovering at 07:26 UTC, Marketing Cloud Personalization at 01:30 UTC, and Heroku at 17:17 UTC, though Marketing Cloud Intelligence dashboard loading issues remained unresolved at the time of the last update.

Impact: A subset of customers in the US-East-1 region may be experiencing performance degradation. Additional Information: Marketing Cloud Intelligence: Dashboard loading issues persist. Recovered Services: Heroku: Recovered at 17:17 UTC MuleSoft: Recovered at 07:26 UTC. Marketing Cloud Personalization: Recovered at 01:30 UTC

We continue to assess the impact across various cloud services. We identified the issue as an infrastructure problem affecting a single availability zone in the US East region.
We're working with a third-party vendor, and are redirecting traffic away from the affected infrastructure. We continue to monitor service health and work with our infrastructure provider toward full service restoration.

We'll provide another update in 60 minutes, or sooner if additional information becomes available.

We continue to monitor all affected services and are engaging our third-party infrastructure provider to accelerate recovery. We're also taking steps to redirect workloads to healthy infrastructure.

We'll provide an update in 60 minutes or sooner if additional information becomes available.

UPDATE 3 days ago - at 05/08/2026 05:12AM

Service recovery is progressing and workloads continue to be redirected to healthy infrastructure. Services that have been moved to healthy infrastructure have recovered and are operating at normal service levels. We have no ETA for when all impacted services will be fully restored at this time.

We'll provide an update in 60 minutes or sooner if additional information becomes available.

UPDATE 3 days ago - at 05/08/2026 08:48AM

We continue to work with our third-party infrastructure provider to restore remaining impacted services in the US-East-1 region where customers may experience slow performance, intermittent errors, dashboard loading issues, or feature access issues affecting Heroku, Marketing Cloud Intelligence, and Marketing Cloud Account Engagement services.

Recovery efforts and infrastructure stabilization activities remain in progress, and workloads continue to be redirected to healthy infrastructure.

Several services moved to healthy infrastructure have recovered and are operating business as usual, including MuleSoft. However, a subset of customers may still experience slow performance, intermittent errors, or feature access issues across some Salesforce services.

We remain engaged in monitoring service health and validating recovery across impacted services.

UPDATE 2 days ago - at 05/08/2026 12:33PM

Our upstream service provider is making progress to resolve this issue and as part of their recovery efforts, a subset of our services are now out of impact. The services which have recovered include MuleSoft, Heroku, and Marketing Cloud Account Engagement.

The only remaining Salesforce service which remains impacted is Marketing Cloud Intelligence. Customers using this service are experiencing issues loading their dashboards.

We don't have an estimated time for when impact to Marketing Cloud Intelligence will be fully restored and are continuing to work with our upstream service provider.

We'll provide an update when have additional information.

UPDATE 2 days ago - at 05/08/2026 12:48PM

Upon further investigation, it has been confirmed that Marketing Cloud Account Engagement customers were incorrectly identified as having been impacted. We apologize for any confusion caused by this.

We are continuing to work with our vendor to resolve the remaining impact to Marketing Cloud Intelligence and will provide an update when additional information becomes available.

UPDATE 2 days ago - at 05/08/2026 01:31PM

We’ve identified that the Marketing Cloud Personalization service was also impacted by this issue. Customers may have received 500 errors when using the service. Remediation steps were taken by routing traffic to a healthy availability zone and this brought customers out of impact at 01:30 UTC.

Work is still underway to resolve the impact to Marketing Cloud Intelligence customers.

We will provide an update when additional information becomes available.

UPDATE 2 days ago - at 05/08/2026 02:52PM

The impact to the Heroku service wasn't resolved as was previously understood. Customers are experiencing that their web apps are failing and returning 500 errors. This is due to the underlying databases being inaccessible.

The latest update from our upstream service provider is that they're still working to resolve the issue on their end.

In parallel, we are evaluating whether we can manually fail over the Marketing Cloud Intelligence service to a different availability zone.

We will provide an update when additional information becomes available.

UPDATE 2 days ago - at 05/08/2026 03:48PM

The Heroku-hosted web applications and customer databases are now fully operational after the migration to a new availability zone. In parallel, we're continuing to evaluate whether we can manually fail over the Marketing Cloud Intelligence service to a different availability zone.
We'll provide an update when additional information becomes available.

UPDATE 2 days ago - at 05/08/2026 04:21PM

While the majority of Heroku customers are now out of impact, we’ve determined that a small subset of customers may still be experiencing a read-only state with their databases. We're actively working to restore full functionality for all remaining affected customers. In parallel, we're continuing to evaluate whether we can manually fail over the Marketing Cloud Intelligence service to a different availability zone.
We'll provide an update when additional information becomes available.

UPDATE 2 days ago - at 05/08/2026 07:19PM

We have successfully applied the fix to all remaining affected Heroku customers and Heroku databases and web applications are now fully operational for all customers.

In parallel, we're continuing to evaluate whether we can manually fail over the Marketing Cloud Intelligence service to a different availability zone.
We'll provide an update when additional information becomes available
