CANTAT-3 is the only NL-16 laser regenerative 2.5 Gig/s submarine system built in the world. Part of this huge system was built at STC Submarine Networks,
Portland, Oregon,
USA, from 1993–1994 (which later became
Alcatel Submarine Networks). STC Submarine Networks in
Southampton,
Hampshire,
UK, made the rest of the system. The Canadian portion (shore end system) was laid off
Nova Scotia by the
Teleglobe cable ship CS John Cabot. The main-lay portion was deployed off Nova Scotia towards the Faroes on board the
AT&T ship Global Mariner. Other cable ships were involved in the completion of this system. This was the northernmost cable system ever deployed at the time. CANTAT-3 was operated by
India's
Teleglobe. On December 17, 2006, CANTAT-3 services were disrupted due to damage to the
submarine cable, resulting in degradation of service to hundreds of thousands of users connecting via internet and media providers (
Síminn,
Vodafone and
Hive). The country was however backed up by the second submarine cable,
FARICE-1 The most notable effect of the event was a temporary shut-down of data communications by Iceland's universities and hospitals, which relied exclusively on CANTAT-3's services. Although it was predicted that a full recovery of the cable would take ten days, starting from midnight on January 13, 2007, it actually took until July 29, 2007 before service was fully restored. During that time, the Icelandic universities and hospitals in
Akureyri and
Reykjavík relied on emergency connectivity obtained via local internet providers
Síminn and
Vodafone. The Icelandic government decided not to buy extra bandwidth for the university network through the functioning
FARICE-1 cable, despite being a large shareholder in FARICE-1. Given that CANTAT-3 suffered multiple interruptions, the alternative cables
FARICE-1,
DANICE and
Greenland Connect were established and/or expanded to ensure cabled telecommunication connectivity in Iceland. CANTAT-3 also had too little capacity by 2007 for domestic Internet usage, and became outdated as soon as the DANICE cable came into operation by 2009. == Usage ==
