Lost both 72 and 77 on 14 July roughly around 6:00 PM or so. Came back within 30 minutes or so. Never experienced that quick a complete outage (Customer since 2004). My bet is on the solar flare activity. The solar sunspot cycle peaks roughly every 11 years. I believe the predicted peak is the May 2013 time frame. Ought to see some interesting events over the next 12 months in my opinion.
