As another anecdote:

In the German I city where I live, Internet access via 4G usually
works well, even though there are noticeable bufferbloat effects
for those who know how to look.

But when there is a significantly higher number of mobile users,
e.g., because of a soccer game or some other event with large
attendance, latency goes up and reaches several seconds with just
light network usage.

Thanks,
