Registry certificate is invalid

[Christian]

Hello,

builds started failing, and chrome displays an error as well, it seems that https://bcr.bazel.build/ certificate is expired?

Best,

[Xudong Yang]

This has been resolved -- please see https://github.com/bazelbuild/bazel/issues/28101#issuecomment-3693346788 for a brief explanation of the outage. There will be a postmortem.

Actually all bazel.build certs seem to have expired:

2025/12/26 17:29:29 could not download Bazel: failed to download bazel: failed to download bazel: HTTP GET https://releases.bazel.build/8.5.0/release/bazel-8.5.0-linux-x86_64 failed: unable to complete 5 requests to https://releases.bazel.build/8.5.0/release/bazel-8.5.0-linux-x86_64 within 30s.

Hi folks,

We're aware of the issue with expired certificates. Normally, these are auto-renewed, but something obviously failed in this case. Working on a manual fix now.
