  6. postmortem

    ### **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.
