Last night I had a dream that my miners were down.  It turns out it wasn't a dream-- I woke up this morning to a dead Internet connection and 9 shifts with 0 hash!

The bad part is I don't know exactly what happened yet.  The problem was on my end-- my firewall became unresponsive.  This morning it was unpingable and every switch port was flashing away like crazy in unison like a broadcast flood.  The only thing running during the night was the miners so nothing should have set off a broadcast storm (or whatever appeared like one), nor has it ever happened before.  After power cycling the firewall everything returned to normal.  I'm left scratching my head as to what happened (and worried it will happen again). 

Anyway, my 6T is back.
