Sonic built-in global CDN

Sonic storage zones (also known as push zones) which have been created with the virtual-hosted style bucket setting have Pushr's global edge network integrated directly without any extra effort required. 

Via the CDN, files uploaded to your buckets will be cached on Pushr's edge servers that are physically closest to the clients who request them, providing maximum performance and low latency for repeated requests. 

Purging the edge cache

When a file is modified or deleeted from your Sonic S3 bucket, the deleted copy may already be in the cache of one or more edge servers. Since automatic purging is not yet implemented, you need to purge the files to remove them from the cache and allow the updated versions to be cached and served to the clients. You can do this via the purge API or from the Cache Purge option in your dashboard.

Deleting an entire zone

When you delete an entire zone, the corresponding bucket that was automatically created for it will also be deleted. The CDN cache will be automatically purged during this action and manual purging is not required.
