Isn't a check every 5 minutes a frequency a bit too high? I mean, if a 
computer is connected to a "captive portal which catches and redirects 
requests", then the chances that the connectivity will change during 
time are very low. In my opinion, having a high frequency will just 
cause unnecessary wakeups and will show boring data in tools used for 
network debugging.

Also, what should happen if the connection to start.ubuntu.com times out 
because of a network congestion? Has this case been discussed? (I wasn't 
at UDS)
