The phone lines at Haverhill Arts Centre have been repaired having been out of action for two days.
BT solved the problem at 4.30pm on Tuesday, July 22.
The box office had been unable to take telephone or online bookings following a lightning on the evening of Sunday, July 20.
The centre was hit at about 7.30pm. Power was knocked off and visible damage was caused to the building, with bricks being blown off into the carpark.
No one was hurt, though a chimney at the rear of the centre was damaged.
The lightning struck at the very beginning of a live broadcast of Monty Python’s Last night of the Pythons.
Nick Keeble, Arts and Leisure Manager at the Haverhill Arts Centre, said: “Things are a bit fluid at the moment. Becuse it was a live performance, we had been hoping to record the performance and repeat it on Friday, obviously this complicates things.
“But we are actively seeking out a performance that was recorded that we can repeat.”
The Monty Python showing has been rescheduled to take place on Sunday, July 27.
Tickets for last Sunday’s cancelled showing will be redeemable, though refunds will be available for those who are unable to attend.
