the problem seems to be in the level3/cenic/losnettos path. juniper -ge- gsr -ge- foundary -ge- foundary -ge- foundary -100m- 7513 the IP path is: juniper - 7513 more as we unearth the problems...
I have two sites (in AS 2116 and 3307) here in Norway which cannot reach the new b.root-servers.net address, 192.228.79.201. No answers to DNS requests, no ping replies, traceroute times out. Everything works normally from a third site, in AS 224.
Both prefixes (193.71.0.0/16 and 194.19.0.0/17) of the problem addresses are visible on route-views.oregon-ix.net, via multiple paths.
Any suggestions why this is happening?
