There seems to be a bug in Onebox where a link is being shown as a Gist when it’s just a Medium article, here’s the link:

[https://medium.com/pragmatic-programmers/circuit-breakers-and-you-ab1281c88f99](https://medium.com/pragmatic-programmers/circuit-breakers-and-you-ab1281c88f99)

(Same thing happening here)

Oh, yikes, we should fix that, looks like a bad regex somewhere @techAPJ can you sort this out.

I believe this is an issue on the Medium side. I am seeing this canonical link in the source of the linked article:

```plaintext
<link data-rh="true" rel="canonical" href="https://gist.github.com/139a99b16e8d1fb37b1b3634b14d9052"/>

```

Onebox library always follows the canonical link.

Other Medium articles are oneboxing fine so it might be a regression in Medium articles with Gist embedded.

We can add [medium.com](http://medium.com) to the list of domains to [ignore canonical tag](https://github.com/discourse/discourse/blob/1472e47aae5bfdfb6fd9abfe89beb186c751f514/lib/onebox/helpers.rb#L10), should we do that @sam? Note that Medium allows custom domains so this will not work in all the cases.
