That was a very interesting read, thanks for the link!
From the article:
The outage in the ephemeris provisioning happened because simultaneously:
* The backup system was not available
* New equipment was being deployed and mishandled during an upgrade exercise
* There was an anomaly in the Galileo system reference time system
* Which was then also in a non-normal configuration
So they had to do a cold boot, which is by design slow because it focuses on high accuracy/certainty. Disappointing to read that the collaboration between the involved companies is downright bad in case of emergencies such as this. And the communication is also terrible, there's no public/official report of what exactly went wrong, why it took so long to recover, and what lessons were learned.
It sounds to me that GPS being under military control is an advantage over Galileo.
