Fiber cuts happen all, the, time. The reason users don't notice is because networks use redundant links. There's really no way to know without doing some serious investigation if it's intentional or not. But my guess would be accidental. A large network like Comcast/L3 is likely dealing with multiple cuts to fiber on a daily basis.
