Here’s the latest word from Vilen
Hey guys, thank you for alerting us of this problem!
@kevin spent all day yesterday trying to get to the cause. The latest, it seems, is that our provider Stream, which handles notifications and feed updates, has been experiencing timeout issues. When this happens, all kinds of problems start to creep up on Cake. It doesn't help that it is a holiday season and it is hard to get to some of the experts until after Christmas. In the meantime, Kevin is doing all he can to keep the site error free.
Please keep us posted about any strange things you are experiencing. It is super helpful!
Will keep you updated as soon as I know more. (Source)
