We are so sorry about the network problem yesterday. We hope that we fixed the issue but nothing is 100% sure.
We will keep monitoring for any abnormal behaviors.
As an apology, we created Happy Hour Boosters for the next 24 hours.
I hope you guys understand there could be some unknown problems once in a while but we will do our best to bring the service as stable as possible.
Once again, thank you very much for your understanding.
Cheers!
