Hey there,
A Looking Glass test only measures our connection to you and some of our internal nodes (As well as some backbone nodes from various network providers) deprioritize connection tests request which make the response post no or extremely high numbers. That is not indicative of an issue. Especially if subsequent nodes appear normal. If data was really being delayed at that node, all nodes after it would show that same delay.
So as the looking glass test stands our connect to your ISP looks great. 0 data loss and latency ends at a solid 29 to 59ms.
This does not show your connection to our services however. To see that data, we recommend running a WinMTR as described here.
I recommend running it while in game/experiencing the issue and let it go for about 10 minutes to get a good data set. Post the results and the community can assist you better.
