  Not surprisingly, the PRDB was as good as the information
  which was submitted by customers of the NSFNET BNS, though
  there was a lot of checking done to try to proactively catch
  mistakes. As someone who was working with/supporting the
  NSFNET configuration process, I do not know of other customers
  claiming that "the PRDB was often in a shambles" via phone, email,
  or third-party reports.
