Why do some features lag more in the evenings?

I’ve noticed a weird pattern lately, certain features start lagging once it hits the evening. Things like bonus rounds loading slowly, spins taking ages, or the balance updating a few seconds late.

From what I’ve seen, it’s usually worst between about 7-10pm. My guess is that it’s simply peak-hour traffic, but it still feels odd how smooth everything is during the day.

Has anyone else had better luck outside peak times? Just keen to understand if it’s my connection or if the platform itself starts slowing down.
