For those still following along:

  1. I am 99% sure I have put a temporary/semi-permanent fix in place for the hourly 2-4 minute downtime that was occurring. Unfortunately a true fix can only come from vBulletin and I am filing a ticket with them shortly.
  2. I have worked out most of an updated PAFOA/vB4 design style and will continue testing it. I'm hoping it can be put into place sometime tomorrow.

Thanks for everyone's patience.
