Due to planned SSMC3 Building Power Maintenance work by Zayo.. impacts were
noted by
NWS forecast offices and NCEP centers and related customers:

- Loss of internet access at NWS field offices from 0314z to 0450z. The
cause noted as DNS issues related to the maintenance work.

- Loss of internet connectivity lost to NCEP web sites during the above
mentioned internet access time.. 0314z to 0450z.  DNS issues/EMWIN issues
developed due to the maintenance work.

- Brief outage noted (by NCO-SS) of no data flowing between NCF and NCO-SS.
from 0417z until approx. 0430z.  NCF noted NWS products getting to SBN fine
at 0436z.  All comms were restored to/from WFO's by 0530z per NCO-SS.

- EMWIN outage from 0314z until 0530z - backlog of data eventually cleared
at 0630z. This outage created a loss of monitoring and internal data flow
between NCO-SS and its customers.  Problems at NCO-SS cleared by 0630z.

Approx 98% of maintenance impacts were restored by 0700Z.  Remaining outage
impacts are being handled by support personnel on a case by case basis and
are mostly seen from systems not yet fully restored due to the maintenance
work - systems didn't come back up on their own.

Zayo maintenance concluded at approx. 1000z.
