NCEP Network Support Branch (NSB) will be performing routine but large maintenance activity effecting the Silver Spring portion of the Level II Network (TDS (Public) path. The activity is a series of routing changes within the Silver Spring and College Park offices supporting the National Level II (NL2) servers.
This change
will CHANGE the TDS IP address.
To ensure you do not lose connectivity to the TDS server, we
ask that you ADD
the following IP address to your ldmd.conf file on the server
ingesting from the TDS.
To ensure no loss of data flow, please ADD the new IP address (REQUEST & ALLOW). Adding vs changing will mitigate the risk of data loss during the cut over to the new IP and minimize path down time from your perspective. We will send out two maintenance notices associated with this migration.
(1) The actual cut
over
Start
Time: 7:00 AM (Central time) (TBD)(Tentatively - The week of May 4th)
Duration: 8 Hours
Event: Silver Spring Networking Updates
(2) A
completion notice (With ACTION Suggested) - to remove the old
IP address)
The
activity will take about 8 hours to complete and will effect
Data flow of the "Silver Spring/TDS Level II Path" for up to
2.5 hours somewhere during that window.
The Data Path via the ROC (Norman, OK) NL2 servers is not
part of this activity.
(No service interruption via RDS path is anticipated.)
Please
keep BOTH NL2 connections (Silver Spring & Norman) up
to avoid data flow interruption.
National Level II (NL2) system monitoring is available on weather.gov
If there is any emergency noted during this event, I can be
reached at (405) 820-3646
Thanks...
