Interesting that your upload speed is SO much higher than download speed??? Doesn't look quite right to me!
It does seem odd...
Pulling a reason out of my butt, I'd guess that the fiber connection is synchronous, and that the measurement has evaluated available bandwidth, which would make sense as people usually download more than they upload, which would reduce the available possible download speed while leaving upload speeds alone.
Not sure though. I'm certain that someone here knows more than me about the subject and could explain why you'd see that.
