Can streaming problems depend on the time of day? And why?

The streaming of arte, 3sat and ZDF via our Firestick obviously depends on the time of day. It works well in the morning, in the evening it is a disaster with constant stutters, stops, etc. Can this be due to the overload of servers? Interestingly, streaming Netflix or Prime content is better at the same time, but not perfect either. Our internet line with an average of 40 Mbps download is good.

I know the problem… This is due to the congestion of the Internet line, which is used much more in the evening. So not on yours but on the one that goes through the street

Depending on the time of day, the service and the internet are used to different extents. In the mornings, people tend to watch less television and it is also common to work at this time. The service and the network are used correspondingly less. In the evenings, people are at home and watch the TV and surf a lot on the Internet, the service is heavily used and the servers and lines reach their limits.

Thanks for the answer! I was afraid of that… However, it is beyond me why Netflix works much better than Arte.

Netflix has more server capacity based on the number of customers.
