On Tuesday, December 1, at approximately 1330 UTC (8:30 a.m. EST), a planned system failover test for up to 8 hours will result in delayed, inconsistent, stale or missing data on the GOES and SPSD web sites and an outage of the OSPO web site. Please monitor for additional information. The failover test may be delayed or suspended if there is a critical weather event.

As a reminder separate from the failover test, GOES-13 Sounder IR data is not available. All products from GOES-13 (GOES-East) Sounder IR data have been halted and distribution has been stopped. Engineers are investigating the problem.
