    ### Dates:

    Monday, June 1st 2026, 13:06 UTC -  15:42 UTC.

    ### What happened:

    Customers served by the US-EAST-4 region were unable to authenticate or start new test sessions because an incomplete TLS certificate chain was deployed to the core directory services.

    ### Why it happened:

    A certificate extraction script defect silently truncated the certificate chain after the certificate authority transitioned to a longer hierarchy.

    ### How we fixed it:

    Reverted the certificate rotation and re-applied the previous known ,good certificate to restore authentication services.

    ### What we are doing to prevent it from happening again:

    Implementing pre-deployment certificate chain validation, adding active monitoring, and fixing the script's chain-length limitations.
