Hi All,


NCO will be performing upgrades on the core Internet routers in College
Park, MD on Wednesday, April 26, 2017.  Please be prepared for intermittent
Internet and NCEP network outages, and associated effects on systems
throughout the maintenance window.

Start Date-Time: 4/26/2017 1015 UTC (6:15 am ET)

Stop Date-Time: 4/26/2017 2015 UTC (4:15 pm ET)

The period of definite impact to users will be 1015 UTC (6:15 am ET) to
1120 UTC (7:20 am ET).  We do not expect a complete outage for the full 50
minutes, but rather intermittent outages of various services during this
window.  There will be a second period of potential impact from 1900 UTC
(3pm ET) to 2015 UTC (4:15 pm ET).  The work during this 75 minutes should
not result in any outages, but it is a high risk period of work that we
want users to be aware of.

The intermittent impacts during the 1015 to 1120 UTC period will affect the
following customers and services:

NWS Customers and Partners;

Outages of NowCOAST, GIS services, and Chart Tile applications hosted on
College Park IDP

Outages of the aviation.weather.gov, tsunami.gov, water.noaa.gov websites

and the Office of the NCEP Director.

NCO will send updates throughout the maintenance window, including when we
are starting and ending the periods where we anticipate impact to users,
and the afternoon high risk period where impact is possible.   After NCO
notifies users that the impactful work is done, you may need to reboot your
workstation or re-establish your connection to the VPN or virtual
machines.  If you have questions or concerns during the maintenance period,
please contact the NCO Senior Duty Meteorologist (SDM) at sdm at noaa.gov or
301-683-1500 <(301)%20683-1500>.

NCO is including our detailed project plan with this notification.  Times
are subject to adjustment once the work has begun.

Thanks,
Chris
