https://static.rust-lang.org/dist/ is flakey

[dwijnand]

Apologies ahead of time if this is the wrong place.

Looks like https://static.rust-lang.org/dist/ is a little flakey, it's failed two CI validation builds that I know of:

• fix a bunch of clippy warnings cargo#5876
• Add support for rustc's --error-format short cargo#5879

The errors is along the lines of:

error: could not download file from 'https://static.rust-lang.org/dist/channel-rust-nightly.toml.sha256' to '/home/travis/.rustup/tmp/o4tx0_y55x5dl6yn_file'
info: caused by: error during download
info: caused by: [28] Timeout was reached (Connection timed out after 30000 milliseconds)

Any ideas?

Maybe it's not tied to rust projects specifically, at the moment I also get download timeouts for ubuntu packages or github repo tarballs across various other projects :/

It is not a problem of https://static.rust-lang.org/dist/, but Travis's connection to GitHub and AWS S3 being flaky. We have already contacted Travis about this issue.

Thanks @kennytm. Is this being tracked somewhere else?

@dwijnand Not tracking issues yet, we're still not sure what is going on. Maybe travis-ci/travis-ci#9112 (comment) is related.
