Overview
- Salesforce confirmed a global service disruption that began on September 16, 2026 and blocked logins, browser access, mobile app functions and API integrations for many customers.
- Engineers traced the failure to an external dependency affecting a legacy login server, blocked a problematic API endpoint as a mitigation, and tested a code fix in a staging environment before wider deployment.
- A validated patch is being rolled out fleet‑wide but recovery is uneven and depends on each customer’s Salesforce instance, so some organizations are already restored while others still see interruptions.
- Outage‑reporting sites recorded large spikes in complaints, with most users reporting website and login errors, and businesses reported stalled dashboards, frozen webhooks and an inability to create support cases.
- Salesforce directed customers to check the Trust Status page for instance‑specific updates; the incident is separate from an earlier browser‑freezing issue the company investigated in early September.
