A power cut has forced businesses to shut up shop for the day.
Some shops on Racecommon Road lost power at about 8.45am on Tuesday, with others being affected about an hour later.
More than 230 properties, both residential and commercial, are affected on Racecommon Road, St George's Road and Grafton Street.
The supply is not expected to be restored until 6pm.
Barber Tony Batty was one of those affected. He said the lights went out half way through a hair cut and he is angry that he has lost a day's custom.
He said: "All of Racecommon Road is shut. I turned up first thing and everything was all right. Power was off at the sandwich shop opposite.
"All that side of the road went out at about 8.05. About an hour later power went here. It's wiped out all business today."
A spokesman for Northern Power Grid said a fault was reported at about 8.45am. Investigations had discovered it was due to a fault in an underground cable.
He said engineers were working on repairing the cable.
