Fire: South Korea Financial District

There was an underground cable fire in the main financial district in South Korea. Several banks and at least one ISP lost high-speed telecommunications service from Friday through Sunday. Although only 33,000 lines were affected, due to the location, they tended to be the very high value lines. A full investigation has been promised. Speaking of full investigations, has anyone heard whatever happened to the investigation into the fire at the telco central office in Toronto's financial district last year?
