I have been having issues talking to Greece on Skype lately through Vodafone. So I see that there is no immediate Vodafone problem, but did a tracert to ntua.gr and came out with this strange result...

It appears that the packets reach telia.net (hop 11) which is in France, and then go back to the states to get re-routed through Frankfurt...

Just wanted to ask the experts in here of how normal is this?

telia in hop 11 is in san francisco.  geoip may be wrong.  hop 12 ping going up prematurely is probably because it's still the latency to the end point rather than intermediate hop.

that route changes providers lots but latency looks ok.  you'd need a lot more samples to check for packet loss/congestion.  maybe using something like pingplotter freeware version.
