We want to try to get this issue worked out before then, so we'll be delaying the Open system at least for now.
As for an announcement: we've made a change that might (or might not) fix the issue. The new change does require a client update, so if you're not able to connect to the website refresh the website and you should be good to go.
The problem is that the issue only manifests itself after a client has been connected to the server for a long time, so we have no way of testing except to leave the website open and see if it happens again. To that end, if you can log in, leave the website open, and see if you have problems (mainly frequent disconnects/reconnects), that would be helpful.
Again, many apologies as we try to isolate and hopefully work around this issue.
