Spectrum says a fiber cable was cut, causing the television and internet service disruption.
An employee reported the damage to fiber optic cables, valued at $30,000, at around 7:50 a.m.
The vandalism is believed to have occurred between 2:30 a.m. and 3 a.m.
Crews immediately began making repairs.
Spectrum is offering a $50,000 reward in the search for the vandals.
Back in June, an employee was arrested for cutting cables, knocking out service to 60,000 customers.
In September wires were cut in Red Hook, Brooklyn.
The company is having an ongoing labor dispute with union IBEW Local 3.
