This morning, in the bathroom off our master bedroom, three electrical outlets along one wall, two on the sides of the double sink, one next to the toilet, suddenly stopped working. Overhead lights, shower exhaust, lights over the sink, etc., continue to work. Outlets in bedroom and another adjacent room work, too. Checked the circuit breaker box in the garage, and all circuits on. Reset the master bedroom circuit breaker anyway. No luck.

What's going on?

Update: Same situation in the bathroom next to our guest bedroom on the other side of our second floor. Two outlets on both sides of double sink are out, as is the outlet next to the toilet. (We had an electrician add the outlets next to the toilets when we bought the place in 2020 in order to install toilet seat bidets.)
