Can anyone confirm that the yarnpkg registry is (partly) down?

Yes, probably related to npm problems <a href="https:&#x2F;&#x2F;status.npmjs.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;status.npmjs.org&#x2F;</a>

Some valid registry urls seems to be broken, for example: <a href="https:&#x2F;&#x2F;registry.yarnpkg.com&#x2F;@styled-system&#x2F;css&#x2F;-&#x2F;css-5.1.5.tgz" rel="nofollow">https:&#x2F;&#x2F;registry.yarnpkg.com&#x2F;@styled-system&#x2F;css&#x2F;-&#x2F;css-5.1.5....</a>

I&#x27;ve had the same problem for a few hours now. I&#x27;m not able to deploy any of my projects.

quick fix would be to use NPM directly<p>(create a `.yarnrc` file with `registry &quot;<a href="https:&#x2F;&#x2F;registry.npmjs.org&#x2F;&quot;`" rel="nofollow">https:&#x2F;&#x2F;registry.npmjs.org&#x2F;&quot;`</a>)
