These services from investigations completed so far are believed to be up and working however they currently do not have resiliency.

From investigations completed so far it is believed that majority of service are up and working for these customers. However work is ongoing to bounce the associated circuits to restore resiliency, and If any are identified as having no service they will be rebuilt as a priority.
