It seems that a Chinese ping-pong ball factory recently started making balls that are slightly larger than the standard size. As a result, ISPs whose tubes are newer, are suffering from pneumatic congestion, kind of like pneumonia if you know what I mean. This isn't affecting the larger ISPs since their tubes are older, and have higher traffic levels. The increased wear on these high-traffic tubes means that they are a slightly larger diameter and the new balls fit through better. The FCC recommends ISPs affected by the flood of these Chinese ping-pong balls to increase air pressure on their tubes to compensate, or to block Chinese traffic from entering their networks.
