Did they have generator backup from the beginning, or we these added 
after the fact? Either way, kudos to clear wire. This last week did not 
give me a lot of confidence in the reliability of cellular 
infrastructure during emergencies, at least as provided by t-mobile. My 
cellular connectivity went up and down all week and I encountered a 
large number of total dead zones while out and about, in areas where I 
know coverage existed in the past. I also experienced a lot of 
irregularity to their service. At one point, I was talking to my brother 
in Cleveland and suddenly got cross connected to someone in Pine Lake 
(the Minnesota variety, by the accent). I also would frequently dial 
numbers, only to be told that they did not exist - not that they weren't 
in service (as in a turned off cell-phone), but that that number was 
unassigned. Redialing the number 15 seconds later had about a 50/50 shot 
of connecting.
