General

Sakura IX is a Internet Exchange (IX) based in Hong Kong, with presence across major data centers including EQHK1, EQHK2, MEGA-i, MEGA-G, MEGA-2, IT2, HKColo, and TGT. Our mission is to make the Internet more open, resilient, and interconnected by providing a neutral and reliable platform where networks can exchange traffic efficiently. By fostering collaboration between carriers, ISPs, content providers, and enterprises, Sakura IX contributes to the growth of a stronger and more accessible Internet ecosystem in Hong Kong and beyond.

Peering requirements

  1. Membership Participants must be a legally registered entity in their local jurisdiction. Participants must hold a valid, publicly registered ASN (Autonomous System Number) assigned by a recognized Regional Internet Registry (ARIN, RIPE NCC, APNIC, LACNIC, or AFRINIC).

  2. Contact Information Participants must provide SakuraIX with 24/7 contact details (email and phone) for technical and administrative issues.

  3. Connectivity Participants should maintain primary global Internet connectivity independent of SakuraIX. SakuraIX is not intended to be used as a primary or sole upstream provider.

  4. Traffic Policy SakuraIX only facilitates the exchange of traffic between members. Participants may not: Transit traffic for non-members. Employ next-hop rewrites, static routing, or policy-based routing that results in traffic not destined for their ASN being forwarded through SakuraIX.

  5. Routing Policy Only prefixes with valid IRR or RPKI records will be accepted. The minimum prefix length accepted is /24 for IPv4 and /48 for IPv6 Bogon, private, or otherwise invalid prefixes will be filtered.

  6. Technical Requirements Participants must operate a BGP-capable edge router for interconnection with SakuraIX route servers. Static routes or non-BGP protocols (e.g., OSPF, RIP, etc.) are not supported. Routers must support standard BGP attributes and best practices (e.g., NO_EXPORT, NO_ADVERTISE, Graceful Restart recommended).

Peering policies

  • Open Peering
    The Member accepts peering requests from any other Member present at SakuraIX without restrictions.

  • Selective Peering
    The Member evaluates each peering request on a case-by-case basis and may apply its own criteria before establishing a session.

  • Restrictive Peering
    The Member defines and publishes specific, objective requirements that must be met in order to establish peering (e.g., minimum traffic volume, geographic presence, routing policies).

  • Paid Peering
    If Members cannot agree on a settlement-free arrangement, they may negotiate a paid peering agreement directly between themselves. SakuraIX is not a party to such agreements.
