That indicates that it has already marked the servers as lame, so the packet trace isn't going to tell you what caused the lameness. The thing to look out for is the minutes before the outage starts - see what kind of failures you get. Also, check the logs for EDNS or lame-servers complaints before an outage starts, which I hope will give you a better idea of how long the problem is (e.g. start off around the 10 minute mark suggested by the lame-ttl setting). Good luck :-) Tony. -- f.anthony.n.finch <d...@dotat.at> http://dotat.at/ - I xn--zr8h punycode South Utsire, Northeast Forties: Southerly or southeasterly 5 to 7, increasing gale 8 at times.
