For most of the last week, Linden Lab's public data/statistical feeds have been showing signs of being a bit ill. Starting on Wednesday evening, concurrency information started to fall ten or fifteen minutes behind actual data - an unusual occurrence. It's only in the last 24 hours that the system has started to catch up again.
At the same time, the figure for active users ceased updating entirely, with the most recent update to that figure being Wednesday night (24 October), at midnight SLT (US Pacific). Perhaps these subsystems are considered relatively minor, but Linden Lab have said themselves that they consider the accurate and ongoing publication of this data critical to their program of transparency.
