The required Space Weather Prediction Center (SWPC) major network upgrade has been rescheduled for May 20 and 21, 2024. On Monday, May 20, the planned time frame for this upgrade work is from 11 a.m. EDT to 5 p.m. EDT (1500-2100 UTC), and operational capabilities will likely be severely limited.
During portions of this period, SWPC will be unable to issue routine products, watches, warnings, and alerts. Access to products and data on the SWPC website will also be impacted and, at times, severely limited to completely unavailable. In the event of significant space weather activity, this maintenance will be postponed.
Additional network upgrades will occur on Tuesday, May 21, between 10 a.m. EDT and 3 p.m. EDT (1400-1900 UTC). This will primarily impact GOES and WCOSS model data (WAM, Geospace, WSA-Enlil), but other intermittent network instability is also possible.
