When the earthquake and tsunami hit Japan back in March, one of the bits of infrastructure that did manage to withstand much of the devastation was telecommunications networks. But that doesn't mean there wasn't damage. Several undersea cables were in fact knocked offline, but the loops did the job they were designed to do. One of those cables was Pacific Crossing's PC-1, whose north link between Ajigaura and Harbour Point and west link between Ajigaura and Shima were both damaged. Yesterday Pacific Crossing and its owner telecom announced that the north link has been repaired, and the west link will be done by late June.
And actually, they did more than fix the north link, they upgraded its capacity to 1.8Tbps also. Since NTT purchased the cable, they have been bulking up the transpacific capacity of their IP network. But it also helps that PC-1 seems to hold the transpacific low latency crown, which puts the cable and its owners in an advantageous position with the financial vertical. That is, when it is fully repaired, as it seems will be the case soon. No doubt other cables off Japan have been under repair as well.
