If you came across gb-lon-anx-r008.router.teamviewer.com and wondered whether it's a scam, the short answer is no. This is not a typical website at all. It's a router hostname used by TeamViewer, a trusted remote-access software company, for internal network infrastructure. The site returns a 404 error and blocks search crawlers because it's not meant to be visited by people. Legitimate businesses often have many such subdomains that serve backend purposes. So when you ask 'is gb-lon-anx-r008.router.teamviewer.com fake?', the evidence says no. The SSL certificate is valid, the domain is clean of any blacklists, and the parent company is well-known. There's no reason to treat this as a risk. Just don't try to browse to itβit's not a webpage.
