From the official Clash of Clans forums
We will have a short maintenance break soon to clean up some space in our databases and keep the servers running smoothly.
At the same, we will be deploying a fix for an issue affecting players’ Personal Break timers. Even though such occurrences are rare, it’s causing some players to hit their PBt earlier than supposed – we’re fixing it!
Finish up those attacks, we’ll be back as soon as possible!
PS: slightly different topic, as many of you have noticed there was a indeed a bug that caused inactive Villages to appear more rarely during multiplayer Matchmaking; this has been addressed and the situation is back to normal now! Thanks for bringing it to our attention!
