“At the mayor’s office itself, I’m able to make outgoing calls, but couldn’t get any incoming calls, so we apologize to all our people for the inconvenience,” said Mayor Fiorentini.

The phone lines were also down in over 500 local businesses. Fiorentini says that’s a big loss for the day.

“Telephones for many businesses are their lifeblood. So, we’re very concerned about our business,” said Mayor Fiorentini.
