In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 17, 2025 - 08:00 PDT

Scheduled - [Update: The beginning of the rollout has been moved to September 24]

PHP Runtime Generation 2 will begin rolling out on September 24 over a 40-day period, starting with dev environments of free sites then gradually moving through all site plans.

What’s New in PHP Runtime Generation 2:
- Support for the latest PHP versions, including PHP 8.4
- Long-Term Support (LTS) editions for PHP
- Updated PHP extensions and improved security features

Recommended Action:
We encourage you to opt into the beta now (https://docs.pantheon.io/php-runtime-generation-2#how-to-opt-in) to verify compatibility with your sites and ensure a smooth transition before the automatic upgrade rollout.

Certain OS packages and PHP extensions are not available with PHP Runtime Generation 2. If your site uses any of the following, we recommend opting out of the rollout for now (https://docs.pantheon.io/php-runtime-generation-2#q-how-do-i-opt-out-of-the-upcoming-platform-rollout):

- IBM PHP ODBC Driver
- wkhtmltopdf
- ioncube
- pdo_sqlsrv
- TLS 1.0-1.1

Salesloft Drift Security Incident: Pantheon Response

Update - We are continuing to monitor for any further issues.
Sep 05, 2025 - 13:52 PDT

Monitoring - Pantheon has been made aware of a widespread security incident impacting companies that use Drift, a third-party vendor used for communicating with visitors on our website via chat. We, and our customers, are affected by this breach.

The Pantheon platform and customer-hosted websites were not impacted.

Our investigation has confirmed that a threat actor exploited a vulnerability in the Salesloft Drift application’s OAuth integration with Salesforce to gain unauthorized access to CRM data. Pantheon was notified on August 28, 2025 of this compromise that occurred between August 12–15, 2025.

The breach resulted in the exfiltration of business information about customer renewals and internal sales account data from our CRM system. While this exposure was limited to Salesforce data connected through Drift, some contact details related to accounts were compromised. Our platform and your hosted websites were not infiltrated and have not been affected.

Upon learning of the incident, Pantheon took immediate steps to contain the threat and safeguard customer data, including:

- Locking down permissions across Salesforce Apps to prevent unauthorized access.
- Removing vulnerable applications associated with Salesforce.

We continue to work closely with Salesforce and Salesloft Drift to conduct a forensic analysis and confirm the full scope of the event. Protecting our customers’ data and maintaining their trust is our highest priority.

As we continue our investigation, we are also conducting thorough reviews of our defenses and security assessments for all third-party integrations. Updates will be shared here as more information becomes available.

If you have questions or concerns, please reach out to your Customer Success Manager.
