KDDI is the carrier and owner of that particular router along the backbone. 195.82.50.234, in particular is the one causing the lag spike. IP address 195.82.50.60 is to be the assumed CPE for SE. I am going to assume KDDI owns the transport for that IP address.

If SE rents the data center, they probably don't have a contract between KDDI and themselves. KDDI and the Data Center has a contract between each other in regards to at least WAN. This isn't that uncommon in the world of ISPs. SE and the data center may have a contract that outlines some network performance SLAs.

SE more-than-likely cannot do anything about this. They can talk to the data center owners to see if something can get done, but more-than-likely, the data center owners won't do anything unless it breaks contract or violates any SLAs.

I am going to assume that this is the last hop router since I am from the USA and I also got that router:

16 118 ms 120 ms 116 ms 195.82.50.60

Though I don't have a huge lag spike when I hit that router. 129 ms is close to industry standard from East Coast USA to Europe. There may be a specific port within the last hop router that is causing the problem.

Regardless, SE cannot do anything about that. Your ISP has to talk to the carrier who owns that router to troubleshoot that particular router and perform a repair. It is still not SE's problem.
