Mostly we are concerned with the downtime. it's not just that 8 hour block, but it's almost once a week the board will be unavailable for 2-10 minutes.
I understand how this site can be slow, due to the heavy cgi processing that has to go on, which is why we are pushing for a php/mysql solution. You do support those right?
Anywho, perhaps we will start keeping a log of fwhen the board is unavailable, to compare with your server logs.
DO you get any advanced notification when outages are expected?
