Yes, all our devices are on the same Internet. I just asked my flatmate and checked if he has the same connection issue as me. He doesn't.
I think I need to ask all my flatmates (+9 ppl) a favor to run through the traceroute on all their connected devices... As I need the worldmap on NR asap, it's easier for me to try another connection in another location (e.g. my friend's apartment).
If any of my flatmate could access to my Pi, could it be that s/he might have messed it up via the shared connection?
