SWPC to Transfer Operations to its back-up site January 19-21, 2016
published: Thursday, January 21, 2016 21:18 UTC

SWPC will be utilizing its back-up processing site starting at 11 am EST (16 UTC) on January 19, 2016 and remaining there until approximately 1 pm EST (18 UTC) on January 21, 2016.  There will be brief outages of SWPC data for upwards of one hour around 11 am EST (16 UTC) on both January 19 and January 21, 2016. 

During the period of time SWPC is running operations from its backup site, updated Ionosonde data on the SWPC ftp server will not be available.  In addition, users will be unable to create new Product Subscription Service (PSS) accounts, or modify their existing accounts, during this period of time.  Alerts from our PSS system for existing accounts will not be impacted except for the brief periods of time mentioned above.
