It's been a day of missed, dropped and failed calls for AT&T wireless customers in Southern California, and the night is sounding very similar.
AT&T spokeswoman Meredith Red said late Saturday that a hardware equipment issue was disrupting service for wireless subscribers in the Los Angeles area, and technicians were working on the problem.
The service glitches began at about 3 p.m. and continued more than six hours later.
It was not immediately clear how widespread the problem was, but users complaining about their lack of service made AT&T one of Twitter's top trending topics for Los Angeles.
Company officials told KCAL and KCBS-TV that there were problems with about 1,000 cell phone towers that were not expected to be fixed until about 2:30 a.m. Sunday.
