I was able to validate the site/sheets up until yesterday. Today while trying to validate I get the error: I/O Error: The host name [www.fayec.com] couldn't be resolved. Details: "www.fayec.com" I was able to validate through another validator and it passed it. Not sure what could be causing this but the issue showed up when trying to validade several urls as well.
Server issue. Should be resolved now. Thanks!
