Kontentai outage history

We experienced service degradation caused by the abuse of missing validation that overloaded our authentication system. As a result, some clients encountered issues accessing the application for approximately one hour. Please note that only access to app.kontent.ai was affected. API availability and performance remained unaffected throughout the incident. The impact occurred primarily during two distinct spikes, lasting approximately 5 minutes and 20 minutes, respectively. Our team identified the root cause, mitigated the immediate impact, and is implementing additional safeguards to prevent similar incidents from occurring in the future.

We are currently experiencing issues with user logins to the application. Our development team is actively investigating the problem, and resolving it is our top priority. We apologize for the inconvenience. We will provide updates as soon as more information becomes available. No APIs are affected. Do not hesitate to contact us at support chat with any questions.

Login functionality has been restored, and we are seeing normal service behavior. The issue stemmed from our authentication provider (Auth0) and has since been resolved. We will continue monitoring to confirm stability.

The service has recovered from the issue, and this incident is now resolved.

Changes to content may not be propagating to the Delivery API and Delivery Preview API in the AUEAST data center. Because of this, webhook notifications also may not be sent as expected.

Our developers are still investigating the root cause, but they have implemented a fix, and changes seem to be propagating successfully to the Delivery API. Webhook notifications also seem to be sending successfully.

The incident has been resolved. All affected services, including the Delivery API and webhook notifications, have fully recovered and are operating as expected.

We are currently experiencing a partial outage affecting the Delivery API and Preview Delivery API. The issue impacts only a subset of content items, which may result in inconsistent behavior for some requests. This is our top priority, and our development team is actively investigating and working on a resolution. If you have any questions or need assistance, please contact our support team via chat.

Update: The issue occurs only for requests that include the excludeElements parameter. Requests that do not use this parameter should function normally. Our developers are working on a fix to mitigate the issue, which is expected to be released soon. Our development team has identified the root cause of the partial outage and is currently working on a fix. Content items that were modified after approximately 9:25 AM (CET) today may be affected. This issue remains our top priority. If you have any questions or need assistance, please contact our support team via chat.

A fix has been implemented and deployed. We are monitoring the results.

We can now confirm that this issue has been resolved. All components are operational and functioning properly.

# Incident summary – Deliver API excludeElements error \(2026-04-15\) ## Summary On 2026-04-15, a change introduced an incompatibility in our content processing that caused some Deliver API requests using the excludeElements query parameter to fail. Specifically, in certain cases an item could be returned without an expected field, and the excludeElements processing path did not handle that scenario. This resulted in an internal error and a 500 response. ## Impact to Customers Customer requests to the Deliver API that included the excludeElements query parameter could intermittently receive HTTP 500 responses during the incident window. The issue affected a limited subset of traffic \(only requests meeting specific conditions were impacted\). The failures occurred only when all of the following were true: * The requested variant \(or one of its dependencies\) had been updated after the deployment. * The request was served uncached \(or required a fresh origin fetch\). * The request included the excludeElements query parameter. ## Resolution ### Timeline \(CEST\): * 08:58 – Deployment completed. * 13:33 – Customer reported errors through Support; we started triage. * 13:37 – Engineering investigation started. * 14:17 – Root cause identified and fix prepared. * 15:32 – Fix deployed. * 16:00 – Service monitored; error rates returned to normal. ### Detection We became aware of the incident after a customer reported the issue via Support. We then confirmed elevated error rates on the affected request path and engaged engineering to investigate and mitigate. ### Guidance During the incident window, retrying the request could succeed depending on whether a fresh fetch was required. If errors were persistent for a specific call, temporarily removing excludeElements would avoid the affected code path \(with the tradeoff of a larger response\). No data loss occurred; this was a request-processing error only. ### Preventive actions * Add end-to-end test coverage for excludeElements, including missing-field scenarios. * Improve automated detection and alerting specifically for elevated 5xx rates on Deliver API request paths. * Add additional safeguards in the API code to handle missing/optional fields defensively. ### Duration Incident window: approximately 08:58–15:32 CEST

A recent Chrome update (version 145) introduced an issue that may lead to occasional CORS errors and HTTP 425 responses when making Delivery API calls. Our CDN provider and the Chromium team are already investigating the root cause. In the meantime, a simple workaround is to update your front‑end to perform a dummy Delivery API request in the background, ignore its errors, and wait briefly before sending further Delivery API requests. Thanks to this, all the other calls should not be affected. Please note that this does not affect users who are using the latest version of our SDK or have a properly implemented retry policy in their codebase. If you have any questions, feel free to contact our Technical Support Team via chat.

We are continuing to work on a fix for this issue.

A workaround has been implemented on our side. The Chromium team is currently testing their fix together with our CDN provider. We are monitoring the situation, and everything should remain fully operational even before their fix is officially released, as our workaround already addresses it.

Following the update implemented by our developers, CORS and HTTP 425 errors no longer occur. After monitoring, we can confirm that the issue is now resolved.

There is currently a delay in the appearance of assets when accessing an asset's preview URL due to our preview storage being overloaded in the U.S. data center. Accessing the published version of an asset still functions as expected.

Our development team has implemented a fix, and accessing an asset via its preview URL after upload is functioning as expected, with minimal delay in processing.

There is currently a delay in the appearance of assets when accessing an asset's preview URL due to our preview storage being overloaded in the U.S. data center. Accessing the published version of an asset still functions as expected.

Delays accessing assets by preview URL have resolved. Accessing both published and preview versions of assets is functioning normally.

We are experiencing a problem in which the Fastly API isn't purging outdated content in the US and EU regions. We are currently investigating the issue and will provide updates as soon as possible.

The problem has been identified as a bug in a recent update. We are working to fix this currently.

This incident has been resolved. Ultimately, the issue stemmed from an error that prevented entities from being deleted in a given database table. All of the failed deletions were manually cleared, and now cache purging works as intended. We will continue to investigate how this occurred, but the Delivery API shouldn't be returning stale content at this point.
