NRIC V Charter 2. Network Reliability.

• (a) The Committee will evaluate, and report on,
  the reliability of public telecommunications
  network services in the United States, including
  the reliability of packet switched networks.
• (c) During the charter of the previous Committee,
  interested participants recommended that the FCC
  adopt a voluntary reporting program, administered
  by the National Communications System, to gather
  outage data for those telecommunications and
  information service providers not currently
  required to report outages. The Committee will
  monitor this process, analyze the data obtained
  from the voluntary trial and report on the
  efficacy of that process, as well as the on-going
  reliability of such services.
