Thank you Carlos, very useful to know the issue is more widespread

If it's useful, here on mirrorservice.org our sync times are about an
hour for

rsync://stage.opensuse.org/opensuse-full/opensuse/

So that's significantly quicker. Maybe we're mirroring a smaller set of
data?

We mirror the same path, and see sync times all over the place. From 16 minutes and up, with a few hours being the most common one, and more than a day occasionally.

Our sync-host is ipv6 enabled and comparing the RTT:s it seems like stage.opensuse.org is really bad at it.

Running mtr -4t stage.opensuse.org and mtr -6t stage.opensuse.org simultaneously in different windows I see 45-ish ms RTT for IPv4 and 80-100ish ms RTT for IPv6. The difference is introduced in the last hop, so it's definitely bad mojo somewhere at or near stage.opensuse.org ...
We see the mtr on ipv6 at about 16 ms RTT and for ipv4 it is about the same.
We are located in Amsterdam, just 2 hops from the amsix and connected with a 10G
