Pantheon Outage History

We are currently investigating degraded performance or failures in platform workflows. This may affect your ability to push code, create environments, or run scheduled tasks. Our engineers are actively triaging the issue and working to implement a fix. We’ll post progress updates regularly on this page.

We are currently observing reduced performance affecting Dashboard loading, though live sites remain unaffected. Our Engineering team is actively investigating the issue and working to restore normal functionality as quickly as possible. We understand this may impact your workflow and appreciate your patience while we work toward a resolution. If you require immediate assistance for general urgent concerns, please submit a support ticket or use live chat. In the event the Dashboard is inaccessible, please contact us directly at [email protected].

Site creation of Drupal 10 and 11 sites are failing due to a security vulnerability recently disclosed in the "symfony/polyfill-intl-idn" library. We are working on a fix to re-enable site creation functionality.

We are currently experiencing an issue causing slow loading times and intermittent errors within the Pantheon Dashboard. All live sites remain fully operational and unaffected. Our Engineering team is actively working to isolate the root cause and restore normal performance. We appreciate your patience as we resolve this deployment blocker. If you require immediate assistance for general urgent concerns, please submit a support ticket or use live chat. In the event the Dashboard is inaccessible, please contact us directly at [email protected].

We are continuing to investigate the root cause of the Dashboard performance issues. Users may continue to experience slow loading times or temporary timeouts. Live sites are unaffected. We are actively working on a fix to restore normal operations. If you need immediate assistance and are unable to access support through the dashboard, please contact us at [email protected].

We are continuing to investigate this issue.

We are continuing to work on the Dashboard performance issues. The dashboard is operating normally. We are continuing to investigate the root cause. All live sites remain unaffected. Our next update will be provided within the hour, or sooner as information becomes available. If you require urgent assistance, please contact [email protected].

We are currently investigating an issue where Git commit logs and deployment histories are unavailable or failing to load on Dev environments. Please be assured that this is a dashboard display issue only: Git pushes and deployments to Dev environments are still processing successfully via the command line (CLI) and Terminus, and all hosted sites remain fully operational. Our Engineering team is actively working to determine the root cause of this display latency and restore Git commit visibility within the dashboard interface. If you are experiencing any issues beyond these specific Git log displays, please reach out to Support via chat or ticket for immediate investigation. We will provide another update within the next 1–2 hours or as soon as more details become available.

Our Engineering team is continuing to investigate the cause of the Dashboard performance issues. Client sites remain unaffected, and we are working to restore full functionality as quickly as possible. For urgent assistance or if the Dashboard is inaccessible, please contact us at [email protected].

Engineering continues to investigate the reported performance delays within the Dashboard. We would like to clarify that all services remain operational and customers should not experience downtime; the impact is strictly limited to Dashboard's page responsiveness. Our next update will be provided in approximately 2–3 hours, or sooner as information becomes available. If you require urgent assistance, please contact [email protected].

We are currently investigating an issue where site traffic metrics are incorrectly displaying as zero within the dashboard. Please be assured that this is a reporting-only issue: all hosted sites remain fully operational, and the dashboard itself is online and accessible. Our Engineering team is working to determine if this is a visual latency error or a delay in the data processing pipeline. If you are experiencing any issues beyond these specific metric displays, please reach out to Support via chat or ticket for immediate investigation. We will provide another update within the next 1–2 hours or as soon as more details become available.

We're currently investigating failure in workspaces, which may affect your ability to create a new workspace. Our engineers are triaging the issue and working on a fix. We'll post progress updates regularly on this page.

We are continuing to investigate the issue.

Our team is continuing to investigate the issue affecting new workspace creation. We apologise for the inconvenience. We will provide an update within the next 3 hours or as soon as new information becomes available.

We are continuing to investigate the issue.

We are currently investigating degraded performance in the deployment workflows from the Test to the Live environment. We have identified a high-risk configuration in the current deployment process that may lead to unintended data and file loss within the live environment. Our engineers are actively triaging the issue and working to implement a fix. We'll post progress updates regularly on this page. We recommend pausing the use of deploy to Live until the issue is resolved.

We are continuing to investigate this issue.

We are currently investigating reports of unauthorized access to a small number of Pantheon customer accounts. Our evidence suggests these accounts were accessed using credentials stolen from external third-party data breaches (unrelated to Pantheon). This technique, known as "credential stuffing," relies on reused passwords. Required Actions for All Customers • Audit Your Sites: Check for unexpected code or file modifications. If you find any suspicious changes, contact Pantheon Support immediately. • Enable MFA (High Priority): Multi-factor authentication is your best defense against password theft. • Enable MFA here: https://docs.pantheon.io/guides/account-mgmt/account/mfa • Update Your Password: If you use your Pantheon password on any other site, change it immediately to a unique, strong passphrase. Next Steps: We are continuing our investigation and will provide further updates as more information becomes available.

We are investigating an issue affecting access to the Pantheon Dashboard, Workflow, and/or the Platform API. Customers may experience errors such as [502 responses, degraded performance, or failed commands]. Our team is reviewing logs and metrics to determine the cause and implement a resolution. We’ll share additional updates here as the situation evolves. We recommend postponing non-critical tasks involving the Dashboard or CLI until the issue is resolved. If you are unable to access the Dashboard and need urgent support, please contact [email protected] for support.
