Is anyone else seeing issues with Level3's DNS servers? We got an alert our mail servers were down but mail is flowing normally, if slowly. Trying to resolve our domain names against Google's 8.8.8.8 and OpenDNS's 208.67.222.222 servers seems fine but 4.2.2.2 and 4.2.2.1 is spotty at best, failing to resolve in most cases.
I'm not seeing any problems with the Dallas-hosted 4.2.2.2: $ time dig +short @4.2.2.2 google.com 173.194.115.7 173.194.115.2 173.194.115.14 173.194.115.5 173.194.115.8 173.194.115.3 173.194.115.4 173.194.115.0 173.194.115.9 173.194.115.6 173.194.115.1 real 0m0.023s user 0m0.012s sys 0m0.000s (Repeated 10 times with similar results) $ time dig +short @4.2.2.1 google.com 173.194.46.4 173.194.46.0 173.194.46.14 173.194.46.3 173.194.46.8 173.194.46.6 173.194.46.2 173.194.46.9 173.194.46.5 173.194.46.1 173.194.46.7 real 0m0.037s user 0m0.008s sys 0m0.004s $ traceroute 4.2.2.2 traceroute to 4.2.2.2 (4.2.2.2), 30 hops max, 60 byte packets 1 <internal ip> 2 olp-67-217-152-5.olp.net (67.217.152.5) 2.719 ms 2.976 ms 3.211 ms 3 router.olp.net (67.217.151.97) 2.322 ms 2.388 ms 2.525 ms 4 olp-67-217-150-202.olp.net (67.217.150.202) 10.949 ms 11.083 ms 11.177 ms 5 vlan1125.car1.dallas1.level3.net (4.28.42.33) 9.912 ms 10.053 ms 10.291 ms 6 ae-2-70.edge2.dallas1.level3.net (4.69.145.75) 10.177 ms 8.414 ms 8.427 ms 7 b.resolvers.level3.net (4.2.2.2) 8.891 ms 8.665 ms 8.903 ms -- Dan White _______________________________________________ Outages mailing list [email protected] https://puck.nether.net/mailman/listinfo/outages
