Codecov uploaders (Action/Orb/Step) fail gpg verification
Timeline · 1 update
- resolved Jun 10, 2026, 03:22 AM UTC
On Saturday, June 6th, the Codecov gpg public key located at keybase.io/codecovsecurity was absent. This caused widespread outages for users uploading with the Codecov - GitHub Action - CircleCI Orb - Bitrise Step In order to quickly move and prevent further outages, the Codecov team deleted the `codecovsecurity` account and created `codecovsecops` with the same public gpg key. This key can be verified against any pre-existing CLI to prove it is the same key and also at about.codecov.io/security. The key location was updated in all of the above uploaders on the latest versions.
Integrity verification on the CLI/Action is failing and blocking uploads to Codecov

Error processing uploads using the global upload token
Timeline · 1 update
- resolved Jan 30, 2025, 07:42 PM UTC
On 28 January from 12:00 to 30 January 13:00 EST There was a disruption to global upload token validation that resulted in the Codecov system accepting uploads but internally denying the upload. This resulted in failed upload processing for repositories configured to use the global upload token. We now have increased monitoring for this scenario and have put measures in place to prevent it altogether. The underlying issue has been resolved and global upload token uploads should again be working as expected.
