Thanks for the feedback everyone, and for confirming you all can log back in and resume playing Starcraft II.
Our engineers have confirmed this is resolved and are working to prevent it from happening again. One of the backend services that Starcraft II uses was having problems, so once that was discovered they were able to get it quickly cleared up.
We are going to close up this thread since we’re good here, but feel free to continue any off-topic discussion in General Discussion. Thanks!
