"issues regarding access and streaming have been resolved" - really?

Update:
For the last 6 days, each day it’s the same (frustrating) experience:
During the daytime (if I have the time), FSim runs quite smooth, loading times are acceptable (could be better in my opinion, but if that’s what we get, I’m fine with it).

In the evening, messages ‘Bandwidth too low’ pop up and loading times are beyond what I consider a playable Sim.
So more often than not I simply give up after staring for 10s of minutes on the swirling circle in the bottom right of the screen.

Am I the only one?
Is this a local (Europe / Germany) problem?
Is this an ISP (Telekom) problem?

My internet-connection usually is about 60-70mbit when measured with Speednet.
