POWR-POWeR outage call list (The Network Outage Call List (POWR)--The POWR PhoneMail list is to be used when all or a large portion of the network users are unreachable via email due to a major power or network outage. This list should be used to inform users of the outage, estimated up time, and any outage updates. Once the problem is resolved, email should be used to inform users that the network is back up. **NOTE: Access to the POWR list is for ML users only** (here is the NCAR "Internal Only" link for the POWR list)
