One of my, by then new girls, had this very unusual active behaviour too. The reason with her were snake mites. After they where gone she became relaxed again. Two little ones always get restless in daytime when they are really hungry. I decided to upgrade the prey size and they became relaxed again. One was active because of a problem with her thermostat. I can give more examples but there is always a reason when they suddenly get restless.
Restless behaviour in daytime is in general caused by stress for one reason or the other. Your mentioned it was only since a few days. Try to find out wether something changed what can cause stress. Maybe a temperature drop or raise because of climate change, or their hide got to small, maybe there is poop in the tank which bother them, or they are simply hungry and it is time to upgrade the rodent size. It is a matter of trying things and watching their reaction. One thing is clear to me, a moving ball python at night is normal, but when I see one of them moving around a lott in daytime I start checking everything. It’s like a human staying up all night not being able to sleep. You only do that when you don’t find your rest ( our you simply want to enjoy some bar time or dancing , but I don’t think snakes stay up for that reason ). Expecially is that is new behaviour and it is more than just one day.
Blacking out all sides except the front is always the best to me with almost all reptiles, even lizards. They always get far more relaxed. With the glass terrariums I use the background posters they also have for fishtanks ( there are some types for terrariums) you can stick on the outside of the enclosure. It even looks very nice, are cheap and because it is on the outside you have no problem with cleaning. I use them really with all our glass enclosure, even the gecko’s, blue tongue skink and bearded dragon.
Here’s an example
Good luck investigating!!!
