It seems we're gotten an influx of lookieloos--890 when I last checked. No idea where they came from, but they obviously like Halloween events!
I rebooted the server to make sure it's not on our end, but it's just a huge amount of traffic mostly loading avatars. The bottleneck is server CPU cores (all running 100%). We have a new 64 core server with 128gigs of ram waiting in the wings, but it's a different OS and there's a lot of software changes that need to before Windlyn can run on it. One day these kinds of issues will be a faint memory...
