Because the AU-NZ cable was down, so AU-NZ traffic over SXC was going NZ-hawaii-fiji-AU..
The cable wasn't down. It looks like they lost one wavelength on the SYD-AKL leg. Vocus and 3 other customers were using that wavelength. No idea who the other customers are, but either they're not making any noise, or they had capacity on other wavelengths which weren't affected.
ahh gotcha, so they were only upgrading gear that Vocus/etc were using and no one else? (Going off latency alone, i'd say KAREN was one of the customers that brought protected capacity)
well i think protected capacity is common, but it shouldn't have to go to the other side of the world unnecessarily? can't there just be redundant waves straight to australia? or was there but not enough to move over?
