NEXRAD Level II Maintenance Notification - Tuesday July 2nd, 2019 (TOC)



Radar Operations Center Engineering will be performing routine maintenance activities to the TOC portion of the National Level II (NL2) Network.  The activity is a software & security upgrade required on NL2 servers supporting the Silver Spring gateway. 

 Start Time: 12:30 AM (Central time)  Tuesday July 2nd, 2019
 Duration: 1 Hour
 Event: TOC NL2 server Software & Security Updates

  The activity will take about 2 hours to complete and will effect Data flow of the "Silver Spring Level II Path" for up to 10 minutes somewhere during that window.  (TDS Path)
 
 The ROC Data Path via the Norman NL2 servers is not part of this activity.
 (No service interruption via RDS path is anticipated.)

Please keep BOTH NL2 client connections up to avoid data flow interruption.


National Level II (NL2) system monitoring is available on weather.gov
