Greetings all, NCEP has just issued the Administrative Alert below. Long story short, NCO network maintenance will occur tomorrow, November 1st, between 11Z - 12Z. Given the breadth of the impacts listed, it's possible (if not likely) that some products may go missing on the IDD. There is no mention of back-filling after the maintenance, so it's not entirely clear if any data these offices would have transmitted during this time will be made available. But as I like to say, uncertainty is the spice of life, so I guess we'll see. SENIOR DUTY METEOROLOGIST NWS ALERT ADMINISTRATIVE MESSAGE NWS NCEP CENTRAL OPERATIONS COLLEGE PARK MD 1626Z TUE OCT 31 2023 ...IMPACTFUL NETWORK MAINTENANCE SCHEDULED FOR TOMORROW (NOV 1)... On Nov 1st, 2023, NCO is performing impactful maintenance on the network. We are migrating two major points of presence from Lumen to NWAVE. The migration will cause an impact when we activate the new connection. The maintenance will occur between 11Z - 12Z. During this time WCOSS will be inaccessible for 10 minutes and intermittently accessible for up to 30 minutes. Also, any site that uses Lumen for OneNWSNet connectivity will be hard down for 10 minutes and will have intermittent network instability for up to 30 minutes. Remote Centers (SPC/Oklahoma WFO/WDTD, NHC/Miami WFO, Kansas City (CRHQ,NIDS, AWC and Learning center), AFWA (Offutt Air Force Base) and Scott Air Force Base), OCONUS Sites (Alaska, Hawaii, Guam, Pacific Region) and ATCSCC Warrenton will not be able to access the Internet or any resources on OneNWSNet during this time. Hawaii Internet will not be impacted. AWIPS traffic to and from the sites listed will be down. SPOT and CMS will be intermittently inaccessible 1100Z and 1200Z.
