Smartsheet Outage History

Between 22:40 UTC on April 21 and 19:21 UTC on April 22, the Workspace Panel was not rendering consistently for users. Regardless of whether they had toggled it on or off, the panel did not appear. The issue was particularly present for non-Enterprise users \(Business and Pro accounts\). The impact was limited to the panel and did not affect any other UI flows within the Smartsheet app. The incident was resolved by rolling back the affected Workspace Panel to a previous known good version.

On Monday, April 13, between 7:00 AM and 11:30 AM PST, some users experienced failures when submitting Smartsheet forms. The issue was isolated to CAPTCHA-enabled forms and was caused by a problem with our reCAPTCHA verification endpoint. Error rates declined significantly by mid-morning and the incident was fully resolved by 11:30 AM PST. All form submissions are operating normally.

On March 30, 2026, at approximately 10:55 PM PDT, the Proofing service encountered issue where users encountered watermarks on all legacy proofs. The outage was caused by a licensing issue and was also compounded by an internal configuration issue causing a full proofing outage. The incident was mitigated by March 31, 2026 at 1:15PM PDT To prevent recurrence, we are conducting a post-incident review focused on improving monitoring and alerting for licensing issues as well bolstering deployment stability.

On March 24, 2026, at approximately 07:55 UTC, the Admin Center Client experienced an issue where users were unable to view user groups in the Group Management view and users in the User Management page in certain cases — instead seeing an infinite loading screen. The issue was caused by a recent update to a shared part of the Admin Center interface that controls how loading indicators are shown during searching. In the Group Management area and UserView, this change accidentally made the page think it was always still loading, so users saw a never-ending loading screen and couldn't view groups \(and in some cases users\). The problem was fixed by rolling back that change, which finalized at 09:06 UTC. To prevent recurrence, we are conducting a post-incident review focused on improving monitoring and alerting for failed page renders in key Admin Center views, adding automated synthetic tests, and documenting recovery runbooks to reduce future resolution time.

On 4:47PM Pacific Standard Time, March 2nd, 2026, a code regression impacted a subset of Form Submissions to propagate to the underlying sheets and some API requests. Service was restored by rolling back to the last known stable deployment. A manual scale up was applied to meet the demands of the queues. Issue was successfully resolved by 9:53AM PST March 3rd, 2026. All previously failed form submissions were successfully replayed by 12:20PM PST, March 4th, 2026.

Approximately on 3:15AM Pacific Standard Time February 22nd, 2026 in our Australia region, a deployment was performed to resolve a performance issue. However, a configuration required to validate session cookies was incorrectly specified, which caused the web app to become inaccessible after successful login. The issue was mitigated within 80 minutes by toggling a feature flag to reroute traffic back to a stable service and full functionality was restored by 4:35AM Pacific Standard Time February 22nd, 2026.

On February 17th, 2026, a failure in the service linking Resource Management Workflows to the main Data Shuttle engine resulted in a service disruption for the Resource Management Advanced Reporting feature in the US Production environment. Service was restored by rolling back the most recent Data Shuttle deployment \(originally released five days prior\). While this action immediately resolved the issue, preliminary analysis indicates the root cause was likely a memory exhaustion issue within the service, rather than a defect in the deployment itself. The rollback effectively reset the service state, clearing the error. A comprehensive RCA is currently underway to pinpoint the source of the outage.

Starting on Monday, February 9th, 2026 at 12:00PM Pacific Time, users experienced blank pages when accessing some Proof generated links. Our engineering team identified a regression. A fix was fully deployed and full proof functionality was restored for all customers on February 10th, 2026 at 11:00AM Pacific Time. We are reviewing our deployment processes to help prevent similar incidents in the future.

Around 7:45pm Pacific Time, our engineering team identified errors when accessing Smartsheet or making changes to assets. We made changes to our infrastructure and and observed gradual recovery. Smartsheet fully recovered at 9:33pm Pacific Time.

On Thursday, December 4th 2025 at 8:08am, users experienced delays in Document Generation requests to download generated documents or attach them to rows. The issue occurred due to increased load on the back end service following a recent code change and was resolved by 11:30am Pacific Time.

On Monday, November 10th, between 12:35 PM and 5:09 PM PST, some users experienced delays in receiving emails. This issue was identified as a regression caused by a recent deployment to our mailing service.We have rolled back the deployment, and email delivery has fully recovered. All queued emails are now being processed.

Beginning at approximately 1:56 PM PDT on October 29, 2025, some customers began experiencing issues accessing https://help.smartsheet.com, due to a disruption with our third-party hosting provider. The fix was fully deployed and service was restored for all customers at approximately 2:50PM PDT.

Beginning on October 29th, 2025, from 8:41AM PDT, users experienced Azure/Microsoft login issues. The issue occurred due to a 3rd party authentication service provider. This was resolved by 5:05PM PDT.

Starting at approximately 4:41 AM PT on October 27, 2025, some Brandfolder customers experienced intermittent delays in receiving system-generated email notifications, including invitations and notifications, due to a disruption with our third-party email processing provider. During this period, emails may not have been delivered immediately. The issue was quickly identified and resolved, and all services were confirmed fully operational by 6:13 AM PT. Any delayed messages are being delivered, and we do not expect further impact.

Beginning at approximately 8:44 AM PDT on October 14, 2025, some customers began experiencing issues accessing attachments and rendering previously set conditional formatting or filters. Our engineering team identified that a recent code change was the cause of the issue and deployed a fix. The fix was fully deployed and service was restored for all customers at approximately 9:57 AM PDT. We are reviewing our deployment processes to help prevent similar incidents in the future.

**Post Incident Summary:** Beginning at approximately 12:52 PM PDT on October 9, 2025, some customers began experiencing issues uploading attachments through WorkApps.

Table View is a recently launched view within Smartsheet, and we have identified that Workflows and Webhooks where the trigger event is an attachment or comment added on Table View will not run. We are working to build this capability. In the interim, using Grid View will mitigate the issue.

On Wednesday, August 27, 2025, from 6:11 a.m. PDT to 7:47 a.m. PDT, some customers may have experienced slow loading and unresponsiveness within the Data Shuttle UI. Our engineering teams were immediately alerted and began investigating the issue. They were able to identify and resolve the problem, and full service was restored at 7:47 a.m. PDT. We are making improvements based on our learnings from the incident to avoid similar incidents in the future.

On August 8th, 2025, starting at 5:15 PM PST, users began experiencing errors and difficulties accessing Smartsheet. By 5:56 PM PST, full service was confirmed to be restored for all users. Our engineering teams quickly determined that a recent internal service deployment was the cause of Smartsheet's unavailability. A rollback of this deployment was initiated, and full service was restored by approximately 5:56 PM PST. We are currently reviewing our deployment processes and internal service dependencies to prevent similar issues in the future.

On July 15th, 2025, starting at approximately 4:54 PM PDT, some users experienced issues accessing and navigating the Smartsheet application. Our engineering teams quickly identified the cause: a recent increase in traffic to a core service overwhelmed another critical internal service, leading to widespread service degradation. Traffic was immediately adjusted, and the affected services were scaled to restore stability. Full service functionality was restored by approximately 5:28
