AS50917 is announced across five independent upstreams and five 100G exchange ports, so no single provider failure takes the network down. Full IPv4 and IPv6 support runs across every upstream and peering session.
Routing objects are maintained under IRR set AS-SITEFAST. RPKI ROAs are maintained for originated prefixes.

Want to peer with us? Send your ASN and preferred exchange to [email protected] or find us on PeeringDB.
Set these on routes you announce to us to control how they're propagated onward. We also tag routes on receipt so you can see where they were learned, both visible live in the looking glass. If you run a session with us and need a community confirmed, our NOC is happy to help.
