I held off posting about this in the hope that the downtime would be short (and thus not worth mentioning), but Boxhat is still down after about 48 hours. Bigred (the site owner) stated that he was hoping to have it back up this morning, but obviously it's not.

Bigred is working on the site problem, and it might come back as early as today. But I think these problems will continue until he permanently changes hosts. His current host has become completely unreliable. However, they're not making to easy for him to switch (being unresponsive to his requests).

March 28th UPDATE: Boxhat is back online. But some recent message posts have unfortunately been lost, due to restoration from a backup.
