Problematic is the unknown provider (aorta seems like some central backone) -> virgin routing which
a) introduces +50ms in ping
b) 2-3% constant PL

EDIT: seems like WinMTR has trouble reverse lookuping the IPs - there is NO WAY that the routing goes with 20ms to Rome - that host should be "war-b2-link.telia.net [62.115.179.208]"

It should be the same apart from the internal datacentre routing.

If possible, I'd use linux "traceroute", as that uses UDP packets like the game, rather than TCP packets which is what windows tracert uses by default.

My theory (currently) based on map change event randomly resetting the pings exactly for 1 MAP (!) is that it has to be some anti-DDOS type of firewall -> the small continuous packets are considered DDOS -> the firewall introduces PL and high ping (either on purpose or as per link - since it is just shit slow) to save the target from having to serve all the requests
Now when typing this & Googling then something from https://subspacepowered.medium.com/how-to-implement-ddos-attack-prevention-mitigation-without-jeopardizing-latency-e8bcdd70a57 sounds similar ->

Code: [Select]

Traditional Security Companies Incur Latency Through Proxying
Current providers regularly rely on proxying traffic as the primary tool for DDoS mitigation. Proxying involves taking the data through a scrubbing server that forwards traffic and runs analysis before sending it back to the user.

Moving data through a proxy for scrubbing increases ping time and latency, resulting in additional lag. It’s only a good solution for web traffic that doesn’t require real-time communications.

The theory is based only on ingame observations by me & Nyrde - when a small disconnect (read: map change) occurs, the ping & PL is fixed (or semi-fixed) exactly for the duration of the next small disconnect (read: another map change). So the theory is ... exactly what it is - a theory
Feel free to comment

EDIT: why would it detect UDP packets as DDOS - because as Pig said "Linux uses UDP to ping" -> for whatever firewall it will not be able to differentiate whether it is a ping attack with huge packets or gaming

am getting packet loss and not good ping,. is unplayable really,. worse than playing on a US server (much worse)

not sure what to do - other than not play,. not everyone is seeing same issue at same time so it's strange one?

Something to consider - UDP routing from Düsseldorf to a slightly different IP

traceroute to 80.4.151.146 (80.4.151.146), 30 hops max, 60 byte packets

Maybe switching the IPs would fix the problems temporarily?
