More Maintenance in the Morning. Here's the info from Pex:

You may have noticed that some of the servers are being a bit... finicky. We have tracked down the cause and are preparing a fix. We won't bring the servers down again this evening. We will prep everything tonight and push the fix live around 9:30am on October 28th is all goes according to plan. The update is scheduled to last an hour.
