The web server was just upgraded to a newer operating system, which also moved it from PHP 7.3 to PHP 8.2. The stats site is old enough that a lot of its code needs updating to run on the new version, so it's offline while that work is done.
Status

Your dataIntact. Nothing was lost.
UpdatesStill processing. Stats are still being collected from every project on the normal schedule, so there will be no gap in history when the site returns.

Other sitesUnaffected. BOINCGames, ut-files, and everything else on this server are working.
