Underwater robot working on severed internet cables

Well there was the news that cables were cut in the mediteranian sea. And you know what, this is the second time in this year.The earlier cut, in late January, was apparently caused by a ship's anchor. Actually these cables carry above 75 % of all Communication traffic between
Europe and the Middle ease.
As per their thoughts an earthquake or trawler net may be the reason behind this damage.Because of which more than 12 countries has got very slow internet access.
A team of specialist engineers, aided by an underwater robot nicknamed Hector, are working on the problem, which they hope will be fixed by Thursday.
