This URL is not a website you'd visit in a browser β it's a backend subdomain belonging to Respawn Entertainment, the studio behind Apex Legends and Titanfall. The domain name itself points to a cross-play service (likely for the game 'R5' or Apex's internal codename). The 503 error you see is temporary, not a sign of a scam. Respawn's infrastructure is hosted on Amazon Web Services with a valid SSL certificate, and no security threats are associated with it. If you encountered this URL in a game log or network request, it's legitimate. For a typical consumer, there's nothing to worry about β this is not a site that asks for personal information or payments. The main thing to watch for with any gaming service is that you're interacting with the official domain, and here the parent domain respawn.com is well-established. r5-crossplay-sub-25.r5prod.stryder.respawn.com is not fake; it's a real part of Respawn's online services.
