Taiwan was the worst affected.

The company forecast it will take two to three weeks for the nation to completely repair the damaged cables. The earthquake also disrupted 1,400 phone lines and 84 international phone lines of Japanese telecom firm NTT, making it impossible to call Southeast Asia from Japan.
