description: >-
  Results of probing the /.well-known/ discovery surface for the AltspaceVR
  domain. AltspaceVR shut down on 2023-03-10 and altvr.com now issues a
  cross-host redirect to https://www.microsoft.com/. Every /.well-known/ path
  therefore returns HTTP 200 only because the redirect lands on the Microsoft
  corporate homepage — none of them served a real, correctly-typed discovery
  document, so nothing was saved verbatim. The developer, docs, api, account
  and status subdomains no longer resolve at all. This is a genuine negative
  result, not a fetch failure.
hosts:
  - host: https://altvr.com
    note: >-
      All paths 30x-redirect off-host to https://www.microsoft.com/ and return
      that HTML homepage. Recorded as redirected-away, not present.
