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 ... /Nikke -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Niklas Edmundsson, Admin @ {acc,hpc2n}.umu.se | nikke@acc.umu.se --------------------------------------------------------------------------- Many pages make a thick book. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= -- To unsubscribe, e-mail: mirror+unsubscribe@opensuse.org To contact the owner, email: mirror+owner@opensuse.org

We are located in Amsterdam, just 2 hops from the amsix and connected with a 10G
