continuation of T365641: Floating IP for Wikispore
Wikispore would like to serve https://wikinyc.wmcloud.org at the domain name map.wikinyc.org.
previously they were talking about using the domain wiki.nyc. I advised that they should only serve content from a domain that they will retain control of indefinitely to make sure that bookmarks, links from other websites, QR codes, etc don't go stale if the domain owner (The City of New York) decides at some later point they don't want to support us any more. we could still serve 301 redirects from the city domain to the chapter domain.
