Re: NEXRAD Level II (NL2) Maintenance Notification - Thursday September 26th, 2019 (Silver Spring)

Radar Operations Center Engineering will be performing routine maintenance activities effecting the Silver Spring portion of the Level II Network (TDS) path.  The activity is software and security upgrades required on National Level II (NL2) servers supporting the Silver Spring.  

 Start Time: 10:00 AM (Central time) Thursday September 26th, 2019
 Duration: 1 hour
 Event: Silver Spring NL2 Server Security and Software Updates

  The activity will take about 1 hour to complete and will effect Data flow of the "Norman/ROC Level II Path" for up to 5 minutes somewhere during that window.  (TDS Path)
 
 The Data Path via the ROC NL2 servers is not part of this activity.
 (No service interruption via ROC 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
