Depends on how angry you are over it and how pessimistic you are.
1. Anand told Chess.com to fake a technical difficulty. Thereby cancelling the match.
2. Anand figured out he would lose and abandoned the game while dancing and whistling a happy tune.
3. Chess.com actually had some real technical difficulties and the game interface crashed. If Anand did not want to play after this, I totally wouldn't blame him.
It just disappeared from my computer, what happenend?
