Album Art Images Failing to Load

I think that the CDN that Apple uses to load the album art for a given song is partially down. Some album arts load fine, and others respond with a 503 (service unavailable). This is seen when trying to request a song like so: https://is1-ssl.mzstatic.com/image/thumb/Music125/v4/7e/de/d1/7eded170-9703-ae08-90c0-dd7c19c2bcac/00602537945665.rgb.jpg/600x600.jpg

Other songs work fine like this one, for example, https://is1-ssl.mzstatic.com/image/thumb/Music115/v4/e8/bd/54/e8bd54fd-6595-4ebf-aa4c-58139ed316e6/dj.bngafruf.jpg/600x600.jpg

This means that album art might fail to load for some albums in Apple Music until this problem is resolved.
