Comment(by nacin):

 `_maybe_update_core()` only triggers an HTTP call if the transient is
 expired. So only once every 12 hours.

 We have _maybe_update_* in case wp cron won't work -- we still want people
 to see updates.

 "Update Network" is the DB upgrade. Doesn't have to do with updating core
 files. What we do there though is make a loopback HTTP request to a file
 in wp-admin that then runs the DB upgrade. Do loopbacks work on your
 server?
