[Tilesathome] Server stuck?

[Alan Millar]

It looks like the TaH server is stuck or dead.  I haven't been able to get
any tiles for a few hours, and the system graphs aren't updating:

I see others have noted it on the wiki Platform_Status page.  Is there a
preferred way to contact someone with admin powers to smack it into
submission, I mean take a look and fix it?

Thanks
