Imagining a Moon colony needing a link to Earth's WWW. Maybe an uplink to a satellite. A link to another satellite in Earth's orbit. A downlink to a server. Maybe 5 minutes for a response time???

A super-server Moon side caching data or constantly scouring Earth WWW for specific data?

Does this make believable sense? What more to consider?

 

The moon is only 1.3 seconds away, so there's no reason for a 5 minute lag.

 

Also, the moon is a horrible place to live. There won't be a moon colony.

 

It won't be a vacation destination, but it's virtually certain that humans will eventually establish a colony on the moon. Perhaps more of a working mine and waypoint than a colony. It's a useful stepping stone to other missions.

Where do you get 5 minutes from? The moon is ≈240,000 miles away. The speed of light is ≈186,000 miles per second. Do the math.
