SG01 terminates TLS and serves cached objects for customer origins across Southeast Asia. It is one point of presence in the Halcyon Edge delivery network — anycast in front, regional shielding behind.
Edge documentationNetwork mapSession resumption and OCSP stapling are handled at the edge. Certificates are issued and rotated automatically; customer keys never leave the origin.
Multiplexed delivery with configurable stream concurrency. Clients that do not negotiate h3 fall back to h2 transparently.
Regional shields collapse concurrent misses into a single upstream fetch, so an origin sees one request instead of a hundred.
Objects continue to be served from cache while a background revalidation runs, keeping p99 flat during origin hiccups.
Tag-based and prefix-based invalidation propagate across the fleet in a few seconds. Purges are idempotent and safe to retry.
Per-request JSON lines with cache disposition, upstream timing and TLS parameters, streamed to an S3-compatible bucket.
SG01 is deployed in a carrier-neutral facility in Singapore and peers regionally. Figures below describe the node configuration, not a service-level guarantee.
