First off: Please DO NOT post any of your details as a reply in this thread as they will contain private information. Rather send us a support ticket with those details; but most importantly open a support ticket with Deutsche Telekom AG about network route instability (if DTAG is your ISP).
Earlier this year then customers of Virgin Media UK experienced a very similar issue as is described in this thread and as we are seeing in metrics now for Germany. See this forum thread: 20220225 - Connection Issues (UK).
See also these posts from me for that incident:

At the time when we were debugging this with Virgin Media UK customer, there was this helpful advice from @Alaska: 20220225 - Connection Issues (UK) - #382 by Alaska
Open a blank text file. Copy the following into your file:
:START
@echo Started: %date% %time%
tracert tranquility.servers.eveonline.com
@echo Completed: %date% %time%
timeout 60
GOTO STARTSave your file (ie filename.bat) to your desired folder. MUST be .bat
Open a Command prompt window. Drag your saved file into the command prompt window (it will show the location when dragged) and hit enter/return to run it.
When disconnected, switch to that CMD window and allow a traceroute to run. Then stop it, and scroll through the latest traceroutes and see if any of them changed; i.e. did the network traffic suddenly go a different route on its way to Tranquility (which is tranquility.servers.eveonline.com // 172.65.201.188). If there is a route change at the time of the disconnect, then we want to hear about it (in a support ticket).
BTW, this issue can’t be fixed in a patch and can’t be fixed on our side. This needs to be fixed by DTAG and Cloudflare, possibly with Level3’s involvement since we have seen Level3 in Frankfurt in traces that have been sent to us.
