SWPC Backup System Testing - TODAY - Thursday, April 2

Backup test
SWPC Backup System Testing - TODAY - Thursday, April 2
published: Thursday, April 02, 2015 21:51 UTC

SWPC is performing a test of its backup processing system today - Thursday, April 2.  The test will be conducted from 1500 UTC to 2100 UTC (1100am - 500pm EDT).  We expect there to be small outages of less than 30 minutes each at both the beginning and end of this test.  After these brief outages, SWPC products will continue to be made available as normal.  If active space weather conditions exist before this test begins, it will be postponed to another date.
