Nor'easter Warning

New England (North East USA) is in the grips of what is being described as a 100 year snow storm. Here at Control.com we are hunkering down and hoping that we don't lose our internet connectivity or electrical power. If we disappear from the internet, please be patient. We'll be back as soon as it is possible.
