#542539 I am currently flying eastwards across EPWW airspace bound for WSSS, with RU-NWC_FSS showing to my north east.
Suddenly CZQX_FSS appears in the Center list. Why :?:

#542544 Hi Richard,

I suspect that this controller had his visibility center set somewhere at 30 degrees West. This way he had a range of 1,500NM (by default) that extended into Poland where you were flying along.
