As I've just posted to the website, forum, etc:
"The web version of Freeciv, play.freeciv.org, was shut down on
3 March 2018. The sole volunteer who was running the service is no
longer willing to continue doing so.
"We haven't identified anyone else on the (very small) Freeciv team who
has the skills and time to run this service hosted on freeciv.org, so
you should expect it to be down for the foreseeable future.
"(I don't know what has happened to the games that were in progress.)"
