hi! can you provide a traceroute, or perhaps www.cloudflare.com/cdn-cgi/trace so I can try to isolate the issue? thanks! -Tom On Tue, Jan 29, 2019 at 10:47 AM Ulf Volmer wrote: > On 29.01.19 16:32, ignat...@cs.uni-bonn.de wrote: > > On Thu, Jan 24, 2019 at 02:22:39PM +0100, ignat...@cs.uni-bonn.de wrote: > >> we've got reports that > >> > >> - repo.anaconda.com (104.17.N.77, 2606:4700::ip.v4.adr.ess) > >> > >> (and later: > >> - www.zabbix.com (104.24.10[23].152, 2606:4700:30::6818:6[6]98) > >> - www.thunderbird.net (104.25.17[45].13, 2606:4700:20::6819:a[ef]0d) > > + www.weatheronline.co.uk (104.18.3[45].125 2606:4700:30::6812:2[23]7d) > > > > Also, we (connected via AS680) are affected, while an AS8422 customer I > > spoke to is not affected. > > > > I was contacted pretty quickly by a CloudFlare engineer who asked for > some > > debug information; they're investigating. > > Hello Igniatos, > > thanks for the update.

I think you should try to ask someone from DFN on a different location if the problem occurs with him too. Best reagards Ulf
