My friend Phil messaged me last night saying he was getting an ERR_SSL_PROTOCOL_ERROR trying to hit up Macc.xyz. Someone showed me the same thing last week at the meetup, and tbh it had me baffled. After some digging (and some curling), we worked out the domain was resolving to 81.99.162.48 for him - not the usual Vercel IPs - which led me to this post on Reddit.

Virgin Media - the unwanted policemen of the web. Seems they’ve applied a default block to .xyz domains.
