Disruptions of submarine communications cables may cause blackouts or slowdowns to large areas. In computer cables it can cause slowdowns or failures of data transfer. Framerate was also improved, with slowdowns becoming rarer. The rerouting of these communications caused large slowdowns in some areas. Between Beijing and Inner Mongolia, only minor traffic slowdowns were reported near toll booths. Slaves resisted by running away, work slowdowns, and revolts. But work slowdowns were the most frequent form of resistance and hard to control. Growth continued at a high rate for most of the 1950s, despite occasional slowdowns. In return GM had relatively few strikes, slowdowns, etc. The subway was affected by a lack of funds, signal slowdowns, and broken-down infrastructure. The human impact on Earth has grown progressively, with few substantial slowdowns. The "industrial ballot" referred to the direct action methods (strikes, slowdowns, etc.) of the IWW. However, such slowdowns are not universal. Some slaves resisted by work slowdowns and by breaking tools and equipment.
