Another Mystery Outage 
Rogers was out again from 6PM Sunday through 2PM Monday. During this outage, repeatedly power-cycling both the modem and the router failed to revive the internet. Lacking the Internet, I was forced to resort to reading Solaris 10 product documentation (which I had fortunately had the foresight to download ahead of time).
According to the monitoring graph, it just came back all on its own in the afternoon while everyone was out.
And Rogers wonders why we don't want Rogers Home Phone service from them.
