I did a traceroute to the first five sites that fail according to the link OP provided (Moscow west 1, Moscow north-east 2, Apatity, Yekaterinburg north and Yekaterinburg south). Here are links to results: http://ping-admin.ru/free_traceroute/result/1644411750rnmh89q0yv38tm0udk6f0.html http://ping-admin.ru/free_traceroute/result/1644411926325hlm41r106780104rjg36.html http://ping-admin.ru/free_traceroute/result/1644412043r4p11366g030gkg3ce2h3.html http://ping-admin.ru/free_traceroute/result/16444121083zs262alh18c545x9u9hj.html http://ping-admin.ru/free_traceroute/result/1644412148591406dtj392t85n5121k.html It looks like three of them are reaching www.postfix.org via Hetzner network and the traceroute stops on host ra.horus-it.com (65.108.3.114) - probably the last one in AS24940. The other two (Moscow north-east 2 and Yekaterinburg south) seem to have their own issues as traceroute doesn't reach outside their own AS (in second case it even doesn't reach past the first hop). -- Regards, Jaroslaw Rafa [email protected] -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
