Update timeline

1. investigating Apr 20, 2026, 01:40 PM UTC

   Status: Investigating We are aware of and investigating errors that started occurring over the weekend as a result of the rotation of our GPG key "rotation of our GPG key": https://discuss.hashicorp.com/t/hcsec-2026-03-hashicorp-gpg-key-72d7468f-update/77237 for [email protected] "[email protected]": mailto:[email protected] (C874011F0AB405110D02105534365D9472D7468F). The errors currently affect the use of Terraform, and hc-install "hc-install": https://github.com/hashicorp/hc-install. Affected components HCP Terraform (Degraded performance)

2. identified Apr 20, 2026, 02:29 PM UTC

   Status: Identified Our engineering team has identified the cause of GPG validation errors with Terraform and hc-install. For hc-install: • A new release has been cut (v0.9.4) which should address key rotation errors. • Affected workflows should update their hc-install version and retry. For Terraform: • Only consumers of Stacks are affected. • Engineers are actively working on a fix. The next update can be expected around 15:00 UTC. Affected components HCP Terraform (Degraded performance)
