Today's whispers seem to indicate other areas around Seattle might want to powercyle to see what is happening in regard to upstream channel bonding.
Edit 9-28-2011: Modem restarted. Upstream channel bonding is gone. Heard a whisper there were some issues, so the second channel was disabled temporarily. No estimate on when it will return, but I have confidence in "my" network guys.
Edit 10-5-2011: It's back now. Received a heads up to powercycle and, sure enough, I have all my blue lights back (send, receive, and connection to my router). Life is good. --
