Looking at our monitoring system it looks like we've lost 3 sites so far tonight (out of 800+ sites). Two sites north of peterson drive and one near Meadowbrooke Apts.
Dan will chase these down first thing the the morning.
EDIT: January 27 - Dan busted his tail today and got every single site back up despite the cold weather.
If you appreciate Dan and Lionell and all the hard work they do, tell them that the next time you talk to one of them.
