Cause:
Following a system upgrade, a CSP noticed that it had been
providing incorrect data to public authorities from its previous
system.
Data Acquired:
Subscriber information relating to an IP address.
Description:
Following a systems upgrade, historical comparisons were
conducted between the new and old data repositories. This
testing found anomalies between the results provided by the
older system and that of the new. The CSP investigated and
found the error to be within the old and not the new system. This
meant that certain sorts of requests, which had only occurred
four times, risked being incorrect. The requesting authorities
were immediately notified. As a result, the authorities did not
take executive action.
Consequence:
The CSP contacted the relevant public authorities, who stopped
any planned action.
