Global CDN · ASC Docs

What it is

Global CDN caches your origin responses at the closest point of presence to each user. Anycast routing picks the optimal PoP per request; smart routing selects the best transit between PoPs and your origin. Tiered caching reduces origin load by serving from regional parent caches before hitting your origin.

When to use it

Static assets, images, video segments, API responses with cacheable headers.
Origins behind expensive bandwidth, where every cache hit saves money.
Global apps that need sub-100 ms first-byte everywhere.

Quickstart

asc edge zones create example.com
asc edge cdn purge example.com --path '/*'
asc edge cdn rules add example.com --match '/static/*' --cache 24h

client.edge.zones.create('example.com')
client.edge.cdn.purge(zone='example.com', path='/*')
client.edge.cdn.rules.add(zone='example.com', match='/static/*', cache_ttl='24h')

await client.edge.cdn.rules.add({ zone: 'example.com', match: '/static/*', cacheTtl: '24h' });
