Please see the following statement form AT&T: “Services for some customers in parts of the Joliet, Shorewood, Minooka, Channahon, Seneca, Marseilles, Ottawa and Peru communities may be affected by a fiber cut in the area. We are working as quickly as possible to make repairs and apologize for any inconvenience this may cause.”
Also note that other cellular carriers may be affected since other carriers (Verizon, Sprint, T-mobile) utilize AT&T fiber for the transport of their signals to their individual cellular systems.
