We are connected to BBIX Singapore but not Hong Kong. We will only peer with Singapore switch participants.

You can ping and trace to ping.as2518.net(both IPv4 and IPv6).

IRR Records should be viewed with source set to RADB or JPIRR. There are colliding records with the same AS-SET name, but from a different AS on RIPE.
