Hi Brian,
Right now, anyone using VATSpy is experiencing what you are. Moreover, anyone using VATSpy, Servinfo or QuteScoop is experiencing the issue.That said, machine2035 and Chris actually answered your question.. "VATSPY/Servinfo get their info from the data servers hence why they are not loading any data in." For VATSpy, SERVINFO or QuteScoop to have content to display (e.g.: flights, a/c, pilots, ATC, etc) they must contact and connect to the VATSIM network of servers. That is mentioned by Chris in his reply containing the excerpt from VATSIM's forum post: "..services involved [affected] are all websites except forums..." This is what VATSpy cannot do at this time -- connect to VATSIM servers. You can, however, still fly online although weather / METARs may not be not current and there has been some strangeness where aircraft disappear and reappear randomly. .
Kind Regards.
