All,

We're going to be testing some new backend server updates again this weekend. Last time this lead to some instability, but we've learned quite a bit from that and have taken steps to make sure it doesn't happen again, with an easy and quick revert path if necessary. There may be some small interruptions, but nothing serious,. There is also nothing you need to do on the client side, this is all on the backend.

Wish us luck, and we'll be watching the results like a hawk for any new issues.
