Hello,
Traffic between sto1.he.net (supposedly in Stockholm, Sweden) and other hosts in Stockholm seem to take very long routes, bouncing across several European countries before finding its way back to Stockholm. This was not so in 2016, but may have started when sto1 went down (and was temporary relocated to Germany?) a few years ago. This adds delays of several tens of milliseconds to tunnel traffic, which used to be in the order of 2ms.
The supplied traceroute output seems to indicate that only IPv4 out from sto1.he.net takes the expected direct route, whereas IPv4 in and all IPv6 traffic takes inefficient routes through twelve99.net.

Yes. Ive noticed that also. :(

The delay was superb before the server died.
Delete/remove twelve99.net. :D ;D
AS1299 had a route loop in their network that they corrected.
This problem seems to have returned.
Traffic from the Stockholm tunnel server goes out through Frankfurt even though it is destined for other hosts in Stockholm. There is also quite a bit of packet loss.
