Broken bibliography link

[Michael-F-Bryan]

I'm rewriting (Michael-F-Bryan/mdbook-linkcheck#11) a lot of the internals for mdbook-linkcheck to take advantage of caching and generate better diagnostics and think I've found a broken link in rustc-guide.

Is anyone able to access GPU Programming in Rust: Implementing High Level Abstractions in a Systems Level Language?

That links is working for me from the USA. It is a PDF.

Hmm, that's interesting. I was getting a "Connection Refused" error from my laptop at home and mobile phone (both behind a VPN), but it works fine from work.

The link isn't actually broken, so this I'll close the issue.
