The hoster that hosted philosopherstones.org had turned off his servers and run away, though the hosting was paid till the end of this year.
The problem is that phs.org is complicated custom python software that requeres postgre database, web proxy, caching etc. All configuration files are lost of course, and I need a few days to configure everything again on a new hosting. And I have no free time now.
I will buy more expensive and reliable hosting and repair phs.org later. Have no exact date, but before the New Year.

But, as before phs community needs somebody who will lead telegram channel, discord channel, reddit, facebook channel maybe, write Medium articles and so on.  Without this work PHS will die, and I can't do this job.
