[IGSMAIL-7065] Re: Network outage on IGS ACC servers -- March 7, 2015

[Stamatakos, Nick]

Hi Kevin —
It seems that the last 2 days of IGS ultras LOD data is suspect.  I cannot say for sure, but in order for us to get our EOP solution to finish, I have to remove the last 2 days of IGS ultra LOD data.

Once we get some VLBI intensives data, I will be able to more definitely inform you if there is a problem or not.

Best regards,
Nick Stamatakos

Subject: [IGSMAIL-7064] Network outage on IGS ACC servers -- March 7, 2015

Author: Analysis Center Coordinator (ACC)

Dear Colleagues:

The hosting facility for the IGS combination servers had experienced
another unplanned network outage before 10:00 EDT on March 7, 2015.
This outage was not recovered until 16:50 EDT, which caused outages
and delays on:

Wk1835_6_12 Ultra-rapid Orbit/Clock,
Wk1834_5 Rapid Orbit/Clock, and
Wk1835_6_18 Ultra-rapid Orbit/Clock products.

All the missing products were recovered between 21:35 and 21:59, and
the Ultra-rapid 1835_0_00 was released without delay.
As a result, Ultra-rapid orbit product (wk1835_6_12) was delayed by 11h:35m
and the wk1834_5 Rapid orbit product was delayed by 9h:35m.

Again, many thanks for your patience. And apologies for any inconvenience
this outage may have caused.

Best regards,
Kevin
