Someone has a dry sense of humor.  Last sentence.

Telepresence SRND, pg 40:

Nonetheless, the network flight-time budget of 150 ms allows for nearly 
24,000 km or 15,000 miles worth of propagation delay (which is 
approximately 60% of the earth’s circumference); the theoretical 
worst-case scenario (exactly half of the earth’s circumference) would 
require only 126 ms. Therefore, this latency target should be achievable 
for virtually any two locations on the planet, given relatively direct 
transmission paths. However, for some of the more extreme scenarios, 
user expectations may have to be set accordingly, as there is little a 
network administrator can do about increasing the speed of light.
