[IGSMAIL-6729] Re: outage interrupts availability of IGS products (SERVICES RESTORED)

[Jake Griffiths - NOAA Federal]

Author: Analysis Center Coordinator

Dear Colleagues,

The servers came back online at approximately 09:02 EST (14:02 UTC). The cause
of the outage is still unknown, but it appears to be from an internet failure
in the Washington, D.C. region.

The missing IGS Ultra-rapid products (1726_0_00 & 1726_0_06) were regenerated
and submitted to the IGS Data Centers. The Ultra-rapid combination at 15:00
UTC happened normally and in time for on-time delivery of 1726_0_12 products.
We expect the Ultra-rapid products to proceed as normal.

We also expect the IGS Rapid products to proceed normally, without delay
today.

Thanks for your patience.

Best regards,

jake
