Peter wrote a post this morning on an exception that was happening site wide (error below). I just emailed Scott to try to come up with a solution, but at first glance it appears to be a bug since there have been no code changes since the upgrade. This means it's been working fine since this weekend and then just crapped out - to fix it i just uploaded a new assembly build (exactly the same one that's up there) which tells me that the item being used that is causing the error was in the cache and it was invalidated.
Will spend day tracking it down. Sorry for the downtime!
