Network Outage Notice for April 23rd

Network Outage Notice for March 6th
Network Outage Notice for April 23rd
published: Tuesday, April 02, 2024 18:48 UTC

On Tuesday, April 23, 2024, between 1500 UTC and 2100 UTC,  the Space Weather Prediction Center plans to perform a major network upgrade that will severely limit our operational capabilities.

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 will be severely limited to completely unavailable.

In the event of significant space weather activity, this maintenance will be postponed.
