Ok, this has to do with the nature of trace-regex, which outputs the whole
thing at the end of the resolve process, with only one timestamp.

Clarified the output a bit to:

Sep 09 20:28:50 [13281] toyotasupplier.com.: Resolved 'toyotasupplier.com.' NS gslb-ns1.toyota-na.com. to:
Sep 09 20:28:50 [13281] toyotasupplier.com.: Trying IP, asking 'toyotasupplier.com.|MX'
Sep 09 20:28:50 [13281] toyotasupplier.com.: timeout resolving after 5000.47msec 
Sep 09 20:28:50 [13281] toyotasupplier.com.: Trying to resolve NS 'gslb-ns2.toyota-na.com.' (2/2)


I also get intermittent failures of toyotasupplier.com here by the way, so
it isn't just you!
