Fault is VM pulling too much traffic through the Interconnect, which cannot be attributed to Telia as it's VM's routing and traffic engineering that decide how much of the internet, how many prefixes they are reaching via Telia, Telia simply advertise everything that is in the agreement with VM.
The traceroute doesn't exonerate VM of blame and a pathping would be of no help it would show the same as the trace presented more prettily.
Tracing route to wow-europe.com [80.239.186.22]

Load lower, spikes lower.
Going straight to the Telia node on a trace it takes an entirely different path which pings better presumably due to avoiding the congested link:

VM just need to sort their traffic engineering out, or alternatively pay Telia more money for transit. It is a transit circuit so very much VM's responsibility to upgrade it, they probably get nasty-o-grams from Telia every so often complaining about overutilisation on it.
