Hi,

Thanks for forwarding the report. I've chatted with the user via IRC on Sunday and subsequently via e-mail, so we're on it. For what it's worth, the underlying issue is still there, although restoring European traffic via the esams (Amsterdam) cluster has significantly reduced the impact.

Regards, Faidon

the routing is broken upstream of our primary IPv6 provider between tele2.net and wikimedia so it may also be affecting other ip6 address ranges
