  • NTT Data's Online Credit Card System Fails Again
  • July 10, 1998 (TOKYO) -- NTT Data Corp. said July 7 that CAFIS (Credit and Finance Information Switching System), its system for automatic authorization of credit card information, went down for a second time, following a five-hour outage on June 16.
    CAFIS is an online network system connecting shops that accept credit cards with credit card companies or banks.

    The system stopped from 9:08 am to 9:41 am on July 7. During that period, authentication of credit card information at 61 credit card companies and 81 financial institutions including banks was halted, preventing transactions from being completed.

    The cause of the problem involved NTT Data's No. 2 host computer.

    After the failure was detected, NTT Data switched the CAFIS operation to the No. 1 machine, which was working normally. The No. 1 and No. 2 computers deal with customer data separately, and each of them is a duplexed system backing up the other. The company is investigating the cause of the computer failure.

    The system outage on June 16 was caused by hardware noise, NTT Data said. When the recovery middleware started working the system crashed due to a bug, which obstructed the automatic system recovery.

    NTT Data officials said that the two separate problems are not related.
