This is a new one for me. . . VPN stopped working, and I cannot access its - or any other VPN website on ANY browser; I get the "can't find the server error"

System info: Mac OS Sequoia 15.3.1, SurfShark VPN, browsers - Safari, Firefox, Brave, DuckDuckGo.

SurfShark will not connect and reports an issue . . .but www.surfshark.com is NOT available . … and ditto for NordVPN, Proton VPN, Epic browser (built-in VPN) websites. I have flushed the DNS cache and still cannot connect to any of these sites. Help!

ISP blocking it maybe?
What about on a different device on same network?
