Questions relating to the INX policy, accounts, membership, eligibility to connect to the INX and other general issues should be addressed to the ISPA secretariat:

Important: JINX Rosebank is full, capacity at JINX Parklands only

JINX has exceeded capacity in the Rosebank facility and has been extended to the neighbouring Parklands building, approximately 100m away. Both facilities are connected by fiber (up to 40GB capacity) for a single virtual JINX environment.

However applications can only be accepted for ports in the JINX Parklands facility so please be aware this might impact on cabling fees levied by the host.
