A service recently forced me to reset my password recently, so I asked them:
Was there an incident that caused passwords to be reset? Was an analysis done on passwords to determine their "strength" such that mine was deemed unfit?
I eventually got this back.
It in fact is exactly what you had guessed. We implemented some measures such as this one to protect yours and all customer information, which is why we had asked you to strengthen your password.

Two years with our orange girls! Happily, they still get along. #mastocats
We brought them home on Halloween two years ago. They've been chasing crinkle balls ever since.
Cats last night, waiting for me to go to bed. #caturday
