Sembra che da alcuni giorni sia inaccessibile tutto il sistema Galileo.
Qui viene indicato lo status di tutti i satelliti.

Another source close to the program told us, “As far as I know, it is a problem of the PTF [Precise Timing Facility] in Italy – time has an impact on the whole constellation!”
The Precise Timing Facility is a ground station that generates the Galileo System Time, or GST. The GST is uploaded to the Galileo satellites to make the user localization possible, and it is also disseminated to every user as an accurate time reference. The Precise Timing Facility hosts several Cesium clocks and a Hydrogen Maser clock.
