Ever since 6.1 patch my latency went from a stable 45ms to 200+ms, nothing changed in my connection to any other service and this only happens when connecting to any European DC, multiple people are having this issue from Portugal for all 4 available ISP's working here.

The only way to "fix" this problem is using a VPN, ever since 6.1 I had to purchase a VPN subscription in order to properly play FFXIV which makes no sense seeing that I use a Portuguese server in my VPN as that gives me the best ping, I currently have better connection to all 3 American DC than any of the 2 European DC by 100ms.

By doing a tracert on the connection I can see its being routed trough New York.

I have a 500mb/s internet connection, it should be more than enough to not get this bad of a latency.

This is the result of the tracert:
