Why is Galileo down?

The EU’s global navigation  satellite system  went down July 11th.   On the 15th,  the GSA blamed the Galileo outage on  “a technical incident related to its ground infrastructure.”   The agency said that the search and rescue (SAR) feature — used for locating and helping people in distress situations for example at sea or mountains — remained operational during the outage,  which impacted only navigational and satellite-based timing services.

That strikes me as ass-covering B.S.,  which the EU is very skilled at producing.   I am a very long way from being satisfied with this sip of information.   It smells like an attack to me,  and I could hazard a guess as to which nations might be behind such a move.
