It seems as though overnight, particularly Sunday night, San Fransisco bay area time, the servers don't seem to be accepting results.
You might calculate the time difference (UTC/GMT-8 hours) and see if you can force the results to be send, i.e. OSX-3.12 -send n where n is the unit number of the rules to be sent.
I noticed a similar problem on USA's Labor Day. It's almost as if the servers are down for backup.
I would try to send the results, but then you might not get credit for them. Of course, as long as the team gets credit...
