  • Resistant: Only minor and/or temporary disturbance(s).
  • Vulnerable: Phone service affecting many phone users could be disrupted for a protracted period, via a sophisticated or coordinated attack.
  • Open: Phone service affecting most phone users could be significantly disrupted indefinitely, via a fairly straightforward assault.
