The fire was in the electrical panel in the basement of the daycare but Beck had to evacuate their offices, affecting service for some customers. Firefighters knocked down the fire just after 5:30 a.m.
Eckerman said damage to the building isn't extensive, but the fire did create a lot of smoke.
In a Twitter message sent just after 7:30 a.m., Beck said their service is returning to normal with only minor delays.
