When does the problem occur (e.g. only during specific times such as in the evenings?)
All the time, but as someone above me mentioned, it's much worse during the evening hours.

Frequency of problem (e.g. every 2 minutes)
Been mining, and I'd say every other swing is delayed. Sometimes by just a little bit, sometimes by several seconds.

Game content in which the issues occur (e.g. dungeons, trials, certain areas)
Absolutely everywhere.
