Which CDNs does plugins.gradle.org use?

Hello,

I am accessing gradle plugins from behind a proxy and would like to verify that the CDN being accessed is managed by or used solely for gradle plugins/ bintray/ jcenter. Requests were sent to this host d29vzk4ow07wi7.cloudfront.net when downloading plugins.

https://plugins.gradle.org/m2/org/eclipse/jetty/jetty-util/8.1.8.v20121106/jetty-util-8.1.8.v20121106.jar

Thank you.
