People here need to get acquainted with an old internet technology which is still active called "newsgroups". Similar to mailing list based forums which are served and repeated by a widely distributed set of voluntary servers. Anyone can setup a server and they automatically synch together.

Often you can set up your offline email readerlike Thunderbird to download newsgroups and you respond to them as you would reply to an email.

Remember if the newsgroup is typical then it will be hosted by multiple newsgroup servers operated independently so they aren't dependent on one server that can be shut down.
