#6012 removes the AWS access keys for publishing to the Mapbox S3 mapbox-node-binaries bucket. Old binaries are still available, but TravisCI will no longer be able to push new ones there.

The reason for this token revocation is https://about.codecov.io/security-update/

We should update our build scripts to push somewhere new - possibly to GitHub Packages?

New releases with published binaries will be blocked until this is fixed somehow.
