Long Island Power Authority, a government-run utility

A 25 year old computer system?  From Fox News:

. . . The New York Post reported that Long Island residents received an estimated rate that covered the entire billing cycle, and the statements made no mention of potential refunds to account for the prolonged blackouts.
"I can't get LIPA to acknowledge my existence on earth to talk to me about anything," Jonathan Saporta told the paper after getting hit with $649 for a home he left in October and $281 bill for his new place. "But I guess they had power, so they could print my bills. Nice, right?" . . .
LIPA also acknowledged that an outdated computer system for keeping customers notified has added to people's frustration.
But some say the government-run utility should have seen it coming. It was recently criticized in a withering state report for lax preparation ahead of last year's Hurricane Irene and for the 25-year-old computer system used to pinpoint outages and update customers. . . .
