Damn, wondered why everything went slow earlier this afternoon...

Edit: The article says that a shunt fault does not kill the signal, but does require urgent repair and downtime.

Not sure of the question but the metal cables within the submarine cable carry several thousand volts, direct current, which power the optical amplifier repeaters

What are the odds of two cable having similar issues at the same time (one one east coast, one on west) and having this happen twice in a year (so far)

Because there are optical signal repeaters on the cable every 100km. They need power. The only way these repeaters can get power is by sending thousands of volts down metail conductors in the optical cable.
