Prisma Access Browser - Intermittent service failures in US region

This incident has been resolved.

We are continuing to monitor the service event impacting the Prisma Access Browser (PAB) in the US region. Our latest investigation indicates that the impact is lower than initially anticipated, and we have confirmed that a majority of users are successfully able to log in, as well as access web and private applications.
Our engineering teams continue to actively monitor the service health and the underlying AWS issue. We will provide a further update as more information becomes available or when the incident is fully resolved.

A critical service disruption has been detected for the Prisma Access Browser (PAB), specifically impacting in the US region. The incident appears to be primarily caused by an AWS service availability issue in the us-east-1 region, leading to significant challenges in token minting and authentication processes.

The service degradation is causing potential access restrictions for users, particularly affecting new users or those who haven't been logged in for over 4 days. Specifically, users may experience difficulties accessing private applications, IDP enforcement, and other related services. Logged-in users are currently less impacted, but new authentication attempts are constrained.

We are currently investigating this issue.
