I have read unconfirmed forum reports that there may be an International issue from 7:57pm impacting High latency to International for Xnet, Orcon and Slingshot.
At this stage I cannot see that this is impacting Telecom NZ nor Telecom
International as far as we can see.
The link between UUNet and Vocus is extremely congested, so may be there that this issue lies.
I have notified Orcon of what I was aware of.
I will update here if I hear anything new.
