There is a large queue processing right now. But, it should all be up and mails coming in as they process
Basically what was supposed to be a quick maintenance had a big issue behind it, and we apologize it was literally supposed to be 5 minutes, but it got into a mess.
The linux team just updated me (sorry but after last night my body went into exhaustion mode, having to go info relay now) that load is normalizing and queues coming down, so you should see normal type activity now.
