uschi01 seems to be fine (at least now that I test it): jeroen@noc:~$ traceroute6 2001:4830:1500:6e::2 traceroute to 2001:4830:1500:6e::2 (2001:4830:1500:6e::2) from 2001:838:1:1:210:dcff:fe20:7c7c, 30 hops max, 16 byte packets 1 fe0.breda.ipv6.concepts-ict.net (2001:838:1:1::1) 0.421 ms 0.368 ms 0.342 ms 2 se2.ams-ix.ipv6.concepts-ict.net (2001:838:0:10::1) 1.992 ms 2.112 ms 1.986 ms 3 ge6-2-0.br0.ams3.nl.gbxs.net (2001:7f8:1::a500:9009:1) 2.36 ms 2.268 ms 2.459 ms 4 2001:1598:b031:2::2 (2001:1598:b031:2::2) 2.986 ms 3.292 ms 3.266 ms 5 ge2-0-0-44.br0.uklon1.realroute.net (2001:1598:a:3::2) 12.061 ms 10.865 ms 12.058 ms 6 2001:7f8:4::31f9:1 (2001:7f8:4::31f9:1) 11.152 ms 11.678 ms 11.084 ms 7 v3323-mpd.cr1.ewr1.us.occaid.net (2001:4830:fe:1010::2) 88.657 ms 88.23 ms 88.562 ms 8 67.ge0-0.cr1.ord1.us.occaid.net (2001:4830:ff:1301::2) 109.653 ms 109.111 ms 109.353 ms 9 sixxs-chcgil-gw.customer.occaid.net (2001:4830:e5:5::2) 109.241 ms 109.436 ms 109.431 ms 10 cl-111.chi-01.us.sixxs.net (2001:4830:1500:6e::2) 212.546 ms !H 209.825 ms !H 210.381 ms !H Except for the 'no host' part being odd, is this issue still there?

From which address are you tracing? Traceroutes help. Ping6 does not. Pinging IRC servers in general is a bad idea as they tend to be ratelimmited. Next to the fact that we really can't care less about IRC servers. And yes, you should open a seperate ticket, this ticket is about sesto01. (Though I would not be surprised if sesto01 issues are sort of related to us* issues)

Thanks for the assistance. There seems to be no problem here either anymore so whatever Michael & I were experiencing on the us POPs must have been temporary. Sorry about posting the information about the us* POPs on the wrong ticket. It won't happen again. You guys run a top notch operation and an awesome public service! Thank you!
