The U.S. Postal Service says it's fixed the electronic glitch that had disrupted some services — and that everything is back to normal.
Spokesman David Partenheimer says in an email that the agency's communication network was restored Friday night.
"Postal Service back up," he says.
A network outage had affected some postal functions from late Thursday through Friday, including package handling at some local post offices. The problem brought down the agency's email system across the country.
The Postal Service says the trouble resulted from a hardware installation Thursday.
The outage did not affect the acceptance of mail, or mail processing or delivery.
