Comment (by Dhalgren):

 Debug-level SafeLogging=1 trace taken while relay was in DNS-frozen state.
 During trace a failed attempt was made to access the news site known for
 having most efficient page design.  One minute fifteen seconds.  Also have
 a SafeLogging=0 trace if it turns out that would make a difference in
 analyzing the issue.
