 Some larger airports shut down entirely, including Boston's Logan International Airport in LaGuardia in New York on Friday. We'll keep you updated.

Another service being impacted by the outage involves a place that many people already dread going anyway, the Department of Motor Vehicles. That part of our coverage from WTOP's Mike Murillo Saturday morning. I do apologize for the inconvenience.
